Question

What is an example of an ion?

Answer 1

`Na^+`, `Fe^(2+)`, `Mg^(2+)`, `Fe^(3+)`, `Ca^(2+)`, `P^(3-)`...

Explanation:

Metals are REDUCING, electron-rich materials, and typically LOSE electrons to form cations...…

`M+DeltararrM^(2+) +2e^(-)`

On the other hand, non-metals, the which are located on the right hand side of the Periodic Table as we face it ... are ELECTRON-POOR, i.e. OXIDIZING materials, and typically gain electrons, cf.

`1/2F_2(g) + e^(-) rarr F^(-)`

`1/2O_2(g) + 2e^(-) rarr O^(2-)`
