Comment upon the statement: A fully filled orbital can participate in bonding.

Short Answer

Expert verified
Generally, fully filled orbitals do not participate in bonding as they are stable and cannot accept more electrons. However, under certain conditions like during the formation of coordination compounds, an electron can be excited to an unfilled orbital which can then engage in bonding.

Step by step solution

01

Understanding Orbitals

Orbitals are regions of space around a nucleus where electrons are most likely to be found. Each orbital can hold up to two electrons. Orbitals can be classified into s, p, d, and f types.
02

Concept of Fully Filled Orbitals

A fully filled orbital is one that contains the maximum number of electrons that it can hold. For example, a 2p orbital is fully filled when it contains six electrons.
03

Participation of Fully Filled Orbitals in Bonding

Typically, partially filled orbitals (those orbitals which are not completely filled) participate in bonding because they can accommodate more electrons. A completely filled orbital does not readily participate in bonding, because it is already stable and has no room to accept more electrons.
04

Exceptions to the Rule

However, under certain conditions, fully filled orbitals can participate in bonding. This usually happens when elements go through excitation, where an electron from a filled orbital is excited to an unfilled orbital. Then, this unfilled orbital can participate in bonding. An example of this is seen in the formation of coordination compounds.
