Question

How does an atom attain stability?

• A. By attaining noble gas configuration.
• B. By having incompletely filled shells.
• C. By having only Helium gas configuration
• D. By having total 10 electrons

Answer 1

The correct option is A By attaining noble gas configuration.

Atoms tend to attain stability when the outermost shell has 8 electrons, i.e. the noble gas configuration. Atoms try to share, lose or gain electrons to attain this configuration.
