Question

The automic number of elements A and B are 12 and 8 respectively. They combine together. Write doun the formula and nature of bonding in the compound

Answer 1

Mg + O2= MgO, ionic bond

Answer 2

$\bf{Answer:}$

Element A = At. no. 12 Therefore, it is Magnesium(Mg)

Element B = At. no. 8 Therefore, it is Oxygen(O)

Now, They combine together
Mg(2) O(2)
Both have valency 2 Therefore its get cancelled. The compound obtained:
$\textit{MgO}$

Nature if bonding,
They are strong ionic bonds which means MgO is ionic bond.

$\textit{Ionic\:Bonds}$: The chemical bonds formed by the complete transfer of electrons from one atom to another are called ionic bonds. Also defined as the strong electrostatic forces of attraction between anions and cations.
