Question

explain why acidic nature of oxides decreases down the group and increases along a period ?

Answer 1

the radius increases and affinity also decreases

Answer 2

Hello dear,

● Acidic character of oxides -
- Oxides are compounds of elements with oxygen.

# Acidic character of oxides decreases down the group because -
- atomic size increases
- metallic character increases
- electronegativity decreases

# Acidic character of oxides increases across the period because -
- atomic size decreases
- metallic character decreases
- electronegativity increases

Hope this helps you.
Thanks for asking..
