4. the spectrum of frequencies emitted caused by electrons moving from low to high energy states
5. rule states that atoms lose, gain or share electrons in order to aquire the stable electron configuration of a noble gas.
7. high energy radiation that has no electrical charge and no mass
8. the minimum amount of energy that can be gained or lost by an atom
10. electrons in an atom’s outer-most orbitals that determine the chemical properties of an element.
11. particle with 2 protons and 2 neutrons like helium
12. the energy levels contained within a principal energy level
14. high speed electron charge that is emitted during radioactive decay
16. An atom or bonded group of atoms with a positive or negative charge.
17. An atom or bonded group of atoms with a positive or negative charge.
21. the rays and particles emitted by radioactmaterialeril
22. shows the atomicatmoic number and mass number of the particle

1. A model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs.
2. the major energy levels of an atom
3. a form of energy that acts wavelike as it travels through space
6. An ion that has a positive charge.
9. shortest distance between equivalent points on a continuous wave.
13. the lowest allowable energy state of an atom.
15. The arrangement of electrons in an atom, which follow 3 rules the aufbau principle, the Pauli exclusion principle, and Hund’s rule.
18. when substances spontaneously emit radiation
19. a particle of electromagnetic radiation with no mass but has energy
20. the number of waves that passes a given point per second
