Answer:

4.has gained two electrons

Explanation:

There exist electrovalent bonding the compound MgS . In electrovalent bonding, there is a transfer of electrons from the metal to non-metal.

Magnesium atom has an atomic number 12 and its electron configuration is 2,8,2

Sulfur atom , a non-metal has atomic number of 16 and its electron configuration = 2,8,6

This means that magnesium as a metal needs to loose two electrons from its valence shell to attain its stable structure.Also sulfur requires two more electron to achieve its octet structure.

Hence a transfer of electrons will take place from magnesium atom to sulfur atom, sulfur gaining two electrons.

Answer:

2. lost two electrons.

Explanation:

Equation of the reaction:

Mg2+ + S2- --> MgS

Therefore, sulphur ion is oxidised while magnesium ion is reduced. In other words, Magnesium ion gains 2 electrons while sulphur ion loses 2 electrons.
