Question

What is the example of cation and anion?

Answer 1

Hi
Here is your answer

For example consider sodium cations (Na+) and Chlorine anions (Cl-). Sodium has a positive 1 charge and chloride has a negative 1 charge. Thus one sodium cation cancels one chloride anion resulting in the formula Na1Cl1 or NaCl.

Answer 2

There can be many possible examples for that..
For cation,
Na+,Ca2+,Al3+,...
For anion.
F- ,Cl- ,O2-....
Hope it helps..
