- 5. Multiple ChoiceWhich two elements only need two valence electrons to be happy?Hydrogen and HeliumLithium and NeonCopper and IronCalifornium and Berkelium
- 6. Multiple ChoiceWhy do Hydrogen and Helium only need two valence electrons?The first electron shell can only hold two electrons.They are both metals.They both begin with H.They are both gases.

- 9. Multiple ChoiceIf Oxygen has 6 valence electrons and is in Group 16 while Chlorine has 7 valence electrons and is in Group 17, what is the rule between group number and valence electrons?Multiply by 2.Take the absolute inverse of the square root.e=mc2Subtract 10.
- 10. Multiple ChoiceHow do ions form?Atoms gain or lose electrons to fill or empty the valence shell.Atoms like cats so they become "pawww-sitive".Atoms gain or lose electrons to change their atomic mass.Atoms gain or lose electrons to match the number of neutrons.
- 11. Multiple ChoiceIf an element gives away an electron, will it form a positive ion or a negative ion?Positive.Pawww-sitive.Negative.Neutral.
- 12. Multiple ChoiceIf an element gains an electron, will it form a positive ion or a negative ion?Positive.Negative.Neutral.Square root of -1.
- 13. Multiple ChoiceWhy does an ion have a charge?There are different numbers of protons and neutrons.There are different numbers of neutrons and electrons.There are different numbers of protons and electrons.There are different numbers for atomic mass and atomic number.
- 14. Multiple ChoiceHow do ionic bonds form?Atoms share electrons to fill their valence shell.Atoms gain or lose electrons to fill their valence shell.Atoms donate electrons to a "sea" of electrons.
- 15. Multiple ChoiceHow do covalent bonds form?Atoms share electrons to fill their valence shell.Atoms gain or lose electrons to fill their valence shell.Atoms donate electrons to a "sea" of electrons.
