Answer 1

Given:

Atomic number of element A = 12

Atomic number of element B = 8

To find:

• Formula of the product formed

• Nature of bonding

Solution:

• From the atomic number, element A is identified as Magnesium, and element B is identified as Oxygen.
• When magnesium reacts with oxygen, it leads to the formation of a product called Magnesium oxide.
• The chemical equation involved in the reaction is as follows:

$2Mg + O_2\rightarrow 2MgO$

• The nature of bonding in magnesium oxide is ionic. This is because, in order to attain octet, magnesium donates 2 electrons and oxygen accepts 2 electron and leads to bond formation.
