Chemistry atomic structure

Atomic structure :

Atoms form ions by losing or gaining electrons to obtain a full outer shell. Here’s a brief overview:

• Metal atoms lose electrons to form positively charged ions (cations).
• Non-metal atoms gain electrons to form negatively charged ions (anions).
• The ions have the electronic structure of a noble gas, with a full outer shell.

The number of electrons in an atom’s outermost shell determines its reactivity and tendency to form chemical bonds with other atoms
