Question

Explain anomalous behaviour of second period of s and p block elements .​

Answer 1

Answer:

All elements are special in their own way even if there are certain trends that have been observed by scientists over the years. The elements belonging to the second period display periodic properties that are especially anomalous.

Let’s take a look at the elements that belong to the second period first:

Explanation:

Answer 2

Explanation:

The second-period elements use 2s and 2p orbitals for bonding. ... Thus anomalous behavior of any group second period element is due to small size, large charge/radius ratio, and high electronegativity of the elements, and covalence cannot exceed four.
