Oxygen would acquire a stable arrangement of electrons by bonding with two atoms of which of the following elements?

sodium

barium

carbon

magnesium

magnesium

Explanation:

Magnesium oxide is a crystalline compound, so that its atoms are organized, a base cell that repeats itself, with the formation of a crystal lattice. The bond between magnesium and oxygen atoms is ionic, therefore it is characterized by being strong and stable in nature. Its crystalline structure is a cubic structure centered on the faces.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

the answer is b & c i believe : )
