Question

Compare alkali metals and halogenswith respect to their valency,atomic size and nature of oxides.Predict the nature of compounds formed between them

Answer 1

Alkali metals and Halogens :-

1. They both have valency 1. Its just thet alkali metals lose 1 electron and Halogens gain 1 electron.

2. The atomic size of alkali metals is bigger than halogens.

3. Alkali metals form basic oxides whereas Halogens form acidic oxides.

They both form ionic bond together.
