Which of the following are likely to form an ionic bond? carbon and hydrogen carbon and sulfur magnesium and sulfur nitrogen and oxygen

magnesium and sulfur

Explanation: Ionic compound is formed by the transference of electrons from metal to non metal.

Magnesium is a metal with atomic number of 12.

Electronic configuration of sodium:

Magnesium atom will loose two electrons to gain noble gas configuration and form magnesium cation with +2 charge.

Sulphur  is a non metal with atomic number of 16.

Electronic configuration of sulfur:

Sulfur atom will gain two electrons to gain noble gas configuration and form sulphide ion with -2 charge.

In Magnesium sulfide , electrons are transferred from magnesium to sulfur.

let that person have a turn to speak : )
