Solids are defined by the following characteristics: Definite shape (rigid) Definite volume. Particles vibrate around fixed axes.

There is no method to designate such properties. The 13 elements that are room temperature gases are radon (Rn), xenon (Xe), krypton (Kr), argon (Ar), chlorine (Cl), neon (Ne), fluorine (F), oxygen (O), nitrogen (N), helium (He) and hydrogen (H).

I presume you mean “What elements are solid at room temperature (and pressure)”. All of them, except the gases hydrogen, nitrogen, oxygen, fluorine and chlorine, the “noble” gases helium, neon, argon, xenon, krypton and radon, and the liquids bromine and mercury.

Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. It is two and a half times heavier than air. It becomes a liquid at −34 °C (−29 °F).

Is Chlorine a Solid, Liquid, or Gas? Chlorine is a solid, liquid or gas. The solid is calcium hypochlorite [Ca(OCl)2], available in granular form or as tablets.

In Cl2 there are covalent bonds between the atoms forming simple molecules. There are weak attractions between molecules of Cl2 meaning little energy is needed to break these forces of attraction and therefore Cl2 has a low boiling point.

What happens to chlorine in the body? When chlorine enters the body as a result of breathing, swallowing, or skin contact, it reacts with water to produce acids. The acids are corrosive and damage cells in the body on contact.

Q: Is chlorine present in the human body? A: Yes, human beings cannot live without chlorine. Our body’s cells exist in a sea of fluid. This fluid is mostly water, along with dissolved charged atoms of sodium and chloride.

Iron is the most abundant transition metal in the human body.
