Question

State whether the following statement is true or false:

Tetra covalent nature of the element with following valence shell electronic configuration is : $1s^2$${2s}^2$ ${2p}^2$ explain on the basis of excitation of $2s$-electrons to $2p$-orbital.

Answer 1

The electronic configuration of Carbon is ${1s}^2$ ${2s}^2$ ${2p}^2$

Since one sub-shell of 2p shell is vacant, one electron jumps from 2s shell to 2p shell creating a covalency of 4. Hence , it is tetra covalent.

Therefore, statement is true.
