Question

Atomic no of 30 elements with electronic configuration and valency

Answer 1

Explanation:

Atomic number = 30

Name of element = Zinc (Zn)

Electronic Configuration = 2, 8, 18, 2

Valency = 2

Answer 2

For example, the names of the subshells in a sulfur atom would be 1s, 2s, 2p, 3s, and 3p (since sulfur has three electron shells). All of these shells are filled except the 3p shell which has four electrons.
