What is the resulting formula unit when magnesium and nitrogen bond

Magnesium (Mg) belongs to group II A in the periodic table with atomic number = 12

Mg Electron configuration = 1s²2S²2p⁶3s²

Nitrogen (N) belongs to group V A in the periodic table with atomic number = 7

N electron configuration= 1s²2s²2p³

Valence electrons for Mg = 2

Valence electrons for N = 5

Mg loses 2 electrons and N gains 3 electrons to complete its octet

Thus, the Formula unit when Mg and N bond is Mg₃N₂

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
