Question

what is periodicity and how do the properties of nature of oxides. change in groups and period​

Answer 1

Explanation:

As electronegativity across a period increases and down the group decreases so, as we move down the group, down the group the atomic size increases.

Hence, basic character increases while as we move across a period its acidic character increases.
