Ionic Bonding Notes
Ionic compounds are formed from a cation and an anion. Opposite charges attract the ions together in an ionic bond. Ions transfer electrons to achieve stable noble gas electron configurations. Ionic compounds have crystalline structures where ions are arranged in repeating patterns. The ions are strongly bonded and give ionic solids properties like brittleness and ability to conduct electricity when molten or dissolved in water.

ATOMS, MOLECULES AND IONS
The document discusses the atomic theory of matter and the development of atomic structure models. It describes John Dalton's atomic theory which stated that elements are composed of atoms that are unique and atoms are neither created nor destroyed in chemical reactions. The discovery of the electron by J.J. Thompson and experiments by Robert Millikan and Ernest Rutherford helped develop the modern atomic structure model of a small, dense nucleus surrounded by electrons. The document also discusses isotopes, atomic numbers, mass numbers, and how the periodic table is arranged based on atomic structure.
Empirical and molecular formula class 11
The document discusses empirical and molecular formulas. An empirical formula shows the simplest whole number ratio of atoms in a compound, while a molecular formula shows the exact number of each atom. To calculate molecular formula from empirical formula: 1) make a table with elements, percentages, atomic masses, moles, and simplest ratios; 2) the empirical formula mass is the sum of the atoms' masses; 3) divide the molar mass by the empirical formula mass to get the common factor for the molecular formula. Two examples are given to calculate empirical and molecular formulas from percentage compositions and molar masses.
How to write a chemical formula
This document discusses how to write chemical formulas. It explains that a chemical formula tells us the types and numbers of atoms in a compound. It then outlines five steps for writing chemical formulas: 1) Write the symbols of the ions side by side in order of positive then negative, 2) Write the valency of each ion, 3) Transfer the valencies to offset them, 4) Omit valencies that are the same, and include different valencies in the formula, 5) For radicals like sulfate and phosphate, the net charge indicates the radical's valency and it is written in parentheses.
Slides on atoms and atomic structure
Atoms are composed of subatomic particles including electrons, protons, and neutrons. John Dalton developed atomic theory, proposing that all matter is composed of indivisible atoms that combine in simple whole number ratios. Atoms consist of a small, dense nucleus surrounded by electrons in energy levels. Rutherford's gold foil experiment revealed the small, dense nucleus at the atom's center. Niels Bohr incorporated quantum theory into atomic structure, proposing electrons orbit in discrete energy levels. The modern atomic model consists of a positively charged nucleus surrounded by electrons in quantized energy shells or orbitals.

Lecture 8.1- Ionic vs. Covalent
The document provides information about ionic and covalent (molecular) bonding:
- Ionic bonds occur between metals and non-metals and involve the transfer of electrons. Covalent bonds occur between two non-metals and involve the sharing of electrons.
- Ionic compounds have high melting and boiling points and conduct electricity when melted or dissolved. Molecular compounds have lower melting and boiling points and do not conduct electricity.
- Ionic compounds exist as crystal lattices of ions, while molecular compounds exist as distinct molecules made of two or more nonmetal atoms bonded together.

ionization energy.ppt
This document provides information about ionization energy for A-level chemistry students. It defines ionization energy as the energy required to remove one mole of electrons from one mole of gaseous atoms. Factors that affect ionization energy include the number of protons in the nucleus and electron shielding. Ionization energy generally increases across a period as nuclear charge increases but decreases down groups as distance from the nucleus increases. Successive ionization energies are always greater than the previous value as electrons are removed from more positively charged species. Large increases indicate removal of an electron from a closer shell.
Ionic Bonding
This document discusses ionic and metallic bonding. It explains that ions are formed when atoms gain or lose electrons to achieve stable noble gas electron configurations. Metals form cations by losing electrons while nonmetals form anions by gaining electrons. Ionic compounds contain cations and anions in ratios represented by chemical formulas. Metallic bonding occurs via delocalized valence electrons that are shared between metal atoms.
Flame tests
This document describes a flame test experiment to identify metals based on the color they produce in a Bunsen flame. The experiment lists various metal compounds and the colors they produce, including lithium (crimson red), sodium (yellow), potassium (lilac), calcium (orange), strontium (red) and barium (green). It explains that the flame heats the metals, moving their electrons to higher energy levels, and as they cool the electrons fall back and emit characteristic colors.
Metallic bonding
Metallic bonding results from the attraction between metal cations and delocalized electrons in the "sea" of electrons. This allows electrons to move freely throughout the metal and form metallic bonds between atoms. Metallic bonding gives metals properties like high melting points, conductivity of heat and electricity, and malleability.

07 lytic vs lysogenic cycle
Bacteriophages can replicate through either a lytic or lysogenic cycle. The lytic cycle involves attachment to a host cell, injection of viral DNA, replication of new viruses inside the host, and lysis of the host cell to release viruses. The lysogenic cycle also involves attachment and injection of viral DNA, but the DNA then integrates into the host genome and replicates with it until inducing lysis. Integrating into the host allows longer replication but slower production of new viruses compared to the lytic cycle.

AP Chemistry - Molecular Orbital Theory
Molecular orbital theory describes how atomic orbitals combine to form molecular orbitals in molecules. When atoms bond, their atomic orbitals overlap and interact to form new molecular orbitals that are shared between the bonded atoms. Electrons occupy these molecular orbitals rather than the individual atomic orbitals. Molecular orbital diagrams illustrate the relative energies of the molecular orbitals and how electrons fill them according to certain rules. Molecular orbital theory can be used to explain bonding properties in diatomic and more complex polyatomic molecules.
Chapter Two Lecture
The document discusses the history and development of atomic theory from Dalton's postulates in the early 19th century to discoveries in the early 20th century. Some of the key developments discussed include:
