Calcium has 2 valence electrons while oxygen has 6 valence electrons. When adding calcium and oxygen together, they form calcium oxide or CaO, and calciums 2 valence electrons join with oxygens 6 to fill the Lewis structure.
Ca 2+ [O with 8e-] 2-
i have this for my homework. im looking for tha answer as well.
2.
Sodium chloride is formed by an ionic bond.
No. This is an ionic compound and the electron of sodium is donated into the electron shell of chlorine. Na + ( the cation ) and Cl - ( the anion ) form the ionic compound NaCl, sodium chloride.
Group 18
Yes, sodium and hydrogen can form the ionic compound sodium hydride (NaH). In this compound, sodium loses an electron to form the Na+ cation, and hydrogen gains an electron to form the H- anion.
