Chemistry module 5

The electrons that are located the highest energy level are called

• ground state electrons

• d-orbital

• valence

• excited

What type of charge do metal ions develop in ionic compounds?

• positive

• negative

• nuetral

• none of them

What does the octet rule say?

• All atoms strive to have 8 electrons

• ll atoms strive to have 8 different orbitls

• almost all atoms strive to have 8 protons

The dots in a Lewis structure represent the

• bonds for each molecule

• entire number of electrons present for each tom

• valence electrons for each atom

• ionic nature of the molecule
