Nuclear chemistry and radiation
Marie Curie discovered radioactivity through her work on atoms and their structure. Nuclear reactions involve changes to the nucleus through loss of particles and rearrangement of protons and neutrons, releasing tremendous energy. There are three main types of radiation emitted in radioactive decay: alpha, beta, and gamma. Half-life refers to the time it takes for half of a radioactive sample to decay and is used in radioactive dating. Radiation is dangerous because it can ionize atoms and damage DNA, disrupting cells.
Nuclear Chemistry
There are two main types of radioactivity: natural and induced. Natural radioactivity occurs in nature from unstable nuclei and can occur through alpha, beta, or gamma decay, each resulting in the emission of different particles or energy from the nucleus. Radioactive decay occurs at a predictable rate and can be used to determine the age of materials through calculation of half-lives. Radioisotopes have many uses including medical tracers, pollution detection, cancer treatment, food preservation, and providing nuclear fuel for power plants.

Radioactivi ty 1
Radioactivity is the spontaneous decay of unstable atomic nuclei through emission of particles or electromagnetic radiation. There are three types of radioactive decay: alpha decay emits helium nuclei, beta decay emits electrons or positrons, and gamma decay emits high energy photons. Not all isotopes of an element are stable, and radioactive decay transforms one isotope into another at a rate characterized by the isotope's half-life and decay constant. The energy and other properties of the emitted particles in radioactive decay depend on the parent and daughter nuclei involved in the transformation.

Nuclear chemistry deals with changes that occur in the nucleus of atoms. These changes are the source of radioactivity and nuclear power. The nucleus contains protons and neutrons, called nucleons. Some atoms are unstable and their nuclei spontaneously break down, releasing particles and energy. Elements whose nuclei emit radiation are radioactive. The spontaneous breakdown of unstable atoms is called radioactive decay or disintegration. There are three main types of radioactive decay: alpha emission, beta emission, and gamma emission. Radioactive decay occurs at a constant rate described by the decay constant. Isotopes are atoms of the same element with different numbers of neutrons, while isobars have the same mass number but different atomic numbers. The half-life of a radioactive
11 Nuclear
Nuclear chemistry involves the study of radioactive decay, nuclear stability, and nuclear transformations. Radioactive decay occurs through alpha, beta, gamma, or positron emission, electron capture, or spontaneous fission. The rate of radioactive decay follows first order kinetics and is characterized by half-life. Radiometric dating uses radioactive decay to determine the age of materials. Nuclear stability depends on having an even number of protons and neutrons and being closest to the nuclear stability belt. Nuclear transformations can change the number of protons through various types of radioactive decay.
Radioactivity
The document discusses the discovery of radioactivity and the different types of radioactive decay:
- Alpha, beta, and gamma decay were discovered through experiments by Henri Becquerel, Marie and Pierre Curie, and Ernest Rutherford in the late 19th century.
- Alpha decay involves emitting an alpha particle (helium nucleus), beta decay involves emitting an electron or positron, and gamma decay involves emitting high-energy photons.
- The decays result in the transmutation of elements and conservation of nucleon number. Radioactive decay occurs at exponential rates described by half-lives and can be used to date materials.

The document also offers tips for dealing with anxiety such as using hand motions and breathing steadily.
Radioactivity
Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two strongest forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation.
Nuclear fission and fusion
Nuclear fission involves the splitting of heavy atomic nuclei into lighter nuclei. It occurs through induced fission where a neutron is absorbed, causing the nucleus to split into fission products along with more neutrons. Nuclear fusion combines two atomic nuclei into a heavier one and releases energy in the process. It is the process that powers stars like our Sun, which generates energy through the fusion of hydrogen into helium in its core.
Chemistry ppt radioactivity
Radioactivity refers to the spontaneous emission of particles or radiation from unstable atomic nuclei and was discovered in 1898 by Henri Becquerel. It has important medical uses such as diagnosing and treating cancer, but also carries dangers if exposed to large amounts. The three main types are alpha, beta, and gamma rays which are classified based on their charge. Radioisotopes are unstable isotopes that decay and emit radiation, and can be used beneficially in areas like medicine, industry, and dating geological materials, though overexposure poses health risks.
Balancing and reaction types
Chemical reactions involve reactants transforming into products. There are several types of chemical reactions that can be identified by their reactants and products. These include synthesis reactions where two reactants combine to form one product, decomposition reactions where one reactant breaks down into multiple products, and displacement reactions where one element replaces another in a compound. Balancing chemical equations ensures the same number and type of atoms are on both sides of the reaction.

Radioactivity occurs when an unstable atomic nucleus loses energy by emitting radiation such as particles or electromagnetic waves. There are three main types of radiation: alpha particles, beta particles, and gamma rays. The rate of radioactive decay is described by half-lives, which is the time it takes for half of the radioactive atoms in a sample to decay. Radioactivity has many uses including cancer treatment, measuring thickness of materials, smoke detectors, and generating electricity through nuclear fission. Radiation can be detected using instruments like Geiger-Muller counters.
Radioactivity.ppt
This document discusses radioactive isotopes and the different types of radiation they emit when decaying. It explains that unstable atomic nuclei will emit alpha, beta, or gamma radiation to become stable. Alpha radiation is emitted as a helium nucleus, beta as a high-speed electron, and gamma as a high-energy electromagnetic wave. It describes the properties and interactions of each type of radiation, and how they can damage cells and potentially cause cancer if absorbed in the body. Examples are given of uses of radioisotopes and radiation such as electricity generation, sterilization, and food irradiation.

Fission and fusion
The document discusses nuclear fission and fusion. Nuclear fission occurs when a nucleus splits into two smaller nuclei and releases neutrons. There are two types of fission: spontaneous fission of unstable radioactive isotopes and induced fission which is caused by bombarding atoms with neutrons. Nuclear fusion occurs when two low mass nuclei combine to form a higher mass nucleus and release energy. Fusion takes place in stars and involves hydrogen fusing to form helium.
Nuclear fission and fushion (ALIV - Bangladesh)
This document provides information on nuclear fission and fusion. It defines fission as the splitting of an atomic nucleus when bombarded by neutrons, which releases energy. Fusion is defined as the joining of atomic nuclei to form heavier nuclei with the release of energy. The document discusses the history of fission's discovery and the processes of fission and fusion in detail through diagrams and explanations. It also addresses differences between fission and fusion such as the energy released and temperatures required for the reactions.

Alpha decay occurs when an unstable atom emits an alpha particle, which is a helium nucleus containing 2 protons and 2 neutrons, becoming a more stable atom. Beta decay is when a neutron changes into a proton and electron, increasing the atomic number by 1 but keeping the mass number the same. Gamma decay releases excess energy from an atom as electromagnetic gamma ray photons after alpha or beta decay.
alpha decay-1-upload.pdf
1. Alpha decay is a radioactive decay process where an unstable nucleus spontaneously emits an alpha particle, resulting in a daughter nucleus with a mass number 4 less and atomic number 2 less than the parent nucleus.
2. For alpha decay to be energetically possible, the Q-value or energy released must be positive. This can be determined by comparing the binding energies and masses of the parent and daughter nuclei based on the binding energy curve.
3. Between mass numbers 144-206, 7 naturally occurring alpha emitters are found, as the binding energy relationship in this range allows alpha decay to be energetically favorable. The lifetimes of these nuclei are long enough for them to remain from their origin in supern
Chapter 21 Nuclear Chemistry Section 2 1Updated (1).pptx
This document discusses types of radioactivity and nuclear decay. It describes alpha, beta, gamma radiation and positron emission. It explains that alpha particles consist of two protons and two neutrons, beta particles are high energy electrons, and gamma rays are high energy electromagnetic radiation without mass or charge. Nuclear decay occurs through radioactive processes like alpha, beta, gamma or positron emission. The rate of radioactive decay is measured by half-life, which is the time for half of a radioactive sample to decay. Radioisotope dating uses half-lives of elements like carbon-14, potassium-40 and uranium-238 to determine the age of materials.

Ch 25 notes
Nuclear reactions involve changes to atomic nuclei, whereas chemical reactions only involve rearrangement of electrons. Nuclear reactions can release large amounts of energy and produce new elements, while chemical reactions typically involve smaller energy changes and atoms remain the same elements. Radioactive decay is an example of a nuclear reaction where an unstable atomic nucleus spontaneously transforms into a more stable nucleus by emitting particles or electromagnetic radiation.

7.2
The document discusses different types of radioactive decay and radiation. It describes alpha, beta, and gamma radiation, and how they interact with and penetrate matter differently due to their mass, charge, and energy. Alpha particles interact strongly, penetrate only a short distance, and produce many ion pairs. Beta particles penetrate farther than alphas as they are lighter and slower. Gamma rays interact weakly and penetrate the deepest as they are uncharged photons. The document also defines half-life as the time for half the nuclei in a sample or half the sample's activity to decay.
P6 radioactive-decay
Radioactive decay occurs when the nucleus of an unstable atom decays and changes. There are three types of radioactive decay: alpha decay which emits a helium nucleus, beta decay which converts a neutron to a proton and emits an electron, and gamma decay which emits electromagnetic radiation without changing the nucleus. Radioactive isotopes are used in medical scans and treatments but are produced artificially in nuclear reactors since they decay naturally over time.
