Question

Beryllium and aluminium have similar properties because
a) they belong to same group
b) they have same charge
c) they have similar electronic configuration
d) they have same polarizing power

Answer 1

they have same polarizing power.
ans d)

Answer 2

Hey dear,

◆ Answer -

(d) they have same polarizing power

◆ Explaination -

- Be & Al exhibit similar properties. This is called diagonal relationship.

- Diagonal relationship exists because crossing & descending in periodic table have opposite effects.

- More appropriately this occurs as they have same polarizing power.

# Similar properties shown by Be & Al -

- electronegativity

- atomic size

- nuclear charge

- polarizing power

- metallic character

Thanks for asking..
