- 2. number the sum of the numbers of protons and neutrons present in the nucleus of an atom
- 4. depicts the electrons as negatively-charged particles embedded in a sea of positive charge
- 8. the property of subatomic particles that causes it to experience a force when placed in an electromagnetic field
- 10. particle that has a negative charge of electricity and travels around the nucleus of an atom
- 12. ions that are negatively charged
- 13. one of the three subatomic particles that make up an atom
- 14. positively-charged nucleus, around which much lighter, negatively-charged electrons circulate, much like planets in the Solar system
- 15. fixed distances from the nucleus of an atom where electrons may be found
- 16. mass the quantity of matter contained in an atom of an element
- 17. an atom or group of atoms that carries a positive or negative electric charge as a result of having lost or gained one or more electrons
Down
- 1. describes the possibility of placing electrons within an atom by describing the principal energy level, energy level, orbital (arbitrary level), and spin of
- 3. number the number of a chemical element in the periodic system and on the periodic table that equals the number of protons in the nucleus of the atom
- 5. atoms with the same number of protons and electrons, but a different number of neutrons
- 6. electrons (negatively charged) revolve around the positively charged nucleus in a definite circular path called orbits or shells
- 7. an ion, or charged particle, with a positive charge
- 9. a subatomic particle with a positive electric charge
- 11. the field of physics that explains how extremely small objects simultaneously have the characteristics of both particles (tiny pieces of matter) and waves (a disturbance or variation that transfers energy)
