Question

Is Chlorine a metal or a non-metal?

Answer 1

Metal and non-metal:

1. In nature, metals are electropositive elements that may transfer electrons. They are hard and strong, malleable and ductile, and good electrical conductors.
2. In nature, non-metals are compounds that can take electrons, i.e. they are electronegative.
3. They are neither malleable nor ductile, and they are poor electrical conductors.
4. Chlorine is a yellowish-green gas that is particularly reactive in nature, reacting with a variety of metals to generate a variety of compounds
5. It has an atomic number$=17$ with an electronic configuration$=1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^5$. It has seven valence electrons and requires one more to complete its octet.
6. Under normal circumstances, elemental chlorine is a bimolecular gas. It generally accepts electrons i.e. an oxidant which is a non- metal's common property.

Therefore, Chlorine is a non-metal.
