UNIT 3 VOCAB
Across
- 4. Cloud Location of electrons(outside of nucleus)
- 9. An element that tends to gain electrons in a bond and is a good insulator
- 11. A measure of how hard an atom pulls on bonding electrons
- 13. The first person credited for arranging elements in order of properties on a periodic table
- 14. A 3D area within a sublevel where there is a high probability of finding an electron
- 15. Rule Empty orbitals fill before electrons begin pairing up
Down
- 1. Law The physical and chemical properties of an element are a function of their atomic number
- 2. An element that tends to loose electrons in a bond and is a good conductor of heat and electricity
- 3. Radius Determines the size of an atom
- 5. The minimum amount of energy that an electron gains/loses when it changes energy levels
- 6. Electrons The electrons in the outer most energy level
- 7. Numbers Set of values that describe the state of an electron
- 8. Effect The effect of the positive nucleus on its outer electrons is reduced by inner electrons
- 10. Element that has some characteristics of metals and some nonmetals
- 12. Energy The amount of energy required to remove the most loosely help electron from an atom
