Question

Identify this symbol. cl-. 1)anion 2)cation 3)atom 4)molecule

Answer 1

Cl- implies that it is a chlorine atom with a negative charge (chloride ion), meaning it is an anion

Answer 2

Answer: Anion

Explanation: Anion is a species which is the negative species formed by the gain of the electrons.

The electronic configuration of Chlorine is

Cl = 1s2 2s2 2p6 3s2 3p5

If an electron has been gained, then it will be placed under the 3p orbital. And as it has been added, it will appear as a negative sign.

Cl- = 1s2 2s2 2p6 3s2 3p6
