Question

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

Answer 1

magnesium and sulfur
(Magnesium is in family two which tends to form ionic bonds)(Elements in families 1 and 2 are very active metals that tend to form ionic bonds)

Answer 2

Answer: magnesium and sulfur

Step-by-step 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:

`[Mg]:12:1s^22s^22p^63s^2`

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

`[Mg^(2+)]:10:1s^22s^22p^63s^0`

Sulphur is a non metal with atomic number of 16.

Electronic configuration of sulfur:

`[S]:16:1s^22s^22p^63s^23p^4`

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

`[S^(2-)]:18:1s^22s^22p^63s^23p^6`

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