Question

a molecule AX2 has 2 lone pairs over A.then its shape is

Answer 1

You did not give the property of element x but if gone through your question it will follow angular shape just like H2O

Answer 2

Shape of the  molecule AX2 is linear.

Explanation:

• Here the molecule $AX2$ has 2 lone pairs over A.
• The molecule $AX2$ which has two bond pairs and no lone pair will have a repulsive force
• In order to minimize the repulsive force between the two bond pairs, the shape of the molecule will have a linear geometry.
• As per VSEPR theory, the molecule AX2 will have a linear geometry and an angle of 180 degrees, here it will have two lone pairs and two bonding pairs.
• Such type of geometry is found in Carbon dioxide molecule
