Matter And Atoms

  1. 1. Matter and Atoms
  2. 2. Matter is… <ul><li>Anything that takes up space. </li></ul><ul><li>Made up of atoms. </li></ul><ul><li>Commonly said to exist in five states or phases: solid, liquid, gas, plasma, or Bose-Einstein condensate, also called BEC (when bosons are confined in an external potential and cooled to temperatures very near to absolute zero. 0K, -273°C or -459.67°F) </li></ul>
  3. 3. Solid
  4. 4. Liquid
  5. 5. Gas
  6. 6. Plasma
  7. 7. BEC
  8. 8. Matter <ul><li>In relativity, matter can be converted to energy via the equation E=mc². </li></ul><ul><li>In cosmology, other forms of matter and energy, such as dark matter and dark energy are invoked to explain the behavior of the observable universe. </li></ul>
  9. 9. ATOMS <ul><li>Are the basis of chemistry and everything in the universe. </li></ul><ul><li>Matter is composed of atoms. </li></ul><ul><li>Atoms are composed of electrons, neutrons, and protons. </li></ul>
  10. 10. Protons <ul><li>A positively charged particle equal to the negative charge of an electron. </li></ul><ul><li>Typically found in the nucleus of an atom, consisting of three quarks (two up-quarks and one down-quark). </li></ul>
  11. 11. Electrons <ul><li>Electrons are the negatively charged particles of atoms. </li></ul><ul><li>Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. </li></ul><ul><li>Electrons are extremely small compared to all of the other parts of the atom. </li></ul><ul><li>The mass of an electron is almost 1,000 times smaller than the mass of a proton. </li></ul>
  12. 12. Neutrons <ul><li>The neutron is a particle found in almost every atomic nucleus. Only the hydrogen nucleus has no neutron. </li></ul><ul><li>It has no electric charge and its mass is nearly 1,840 times that of the electron. </li></ul><ul><li>Neutrons and protons make up almost all of an atom's mass. </li></ul><ul><li>Like the proton and other baryons, the neutron consists of three quarks. </li></ul><ul><li>A free neutron (one not contained in an atomic nucleus) is radioactive. It undergoes beta decay to form a proton, an electron, and an electron-antineutrino. This what happened to most of the neutrons created by the big bang. </li></ul>
  13. 13. Question 1 <ul><li>Name the five states of matter. </li></ul>Answer: Solid, Liquid, Gas, Plasma, and BEC
  14. 14. Question 2 <ul><li>What is matter composed of? </li></ul><ul><li>Water </li></ul><ul><li>Molecules </li></ul><ul><li>Chemicals </li></ul><ul><li>Atoms </li></ul>Answer: d
  15. 15. Question 3 <ul><li>What are atoms composed of? </li></ul><ul><li>Protons </li></ul><ul><li>Neutrons </li></ul><ul><li>Electrons </li></ul><ul><li>All of the Above </li></ul>Answer: d
  16. 16. Question 4 <ul><li>Do electrons have a negative or positive charge? </li></ul>Answer: Negative
