Chemistry
Explain the reason for chemical activity of an atom with reference to it's electronic configuration.
Answer
Reasons for chemical activity of an atom are:
- Unstable electronic configuration — Atoms of elements other than noble gases are assumed to have unstable electronic configuration.
- Attaining stable electronic configuration — The driving force in combination of atoms is related to the tendency for them to attain a stable electronic configuration of the nearest noble gas.
