Question

What nonmetals (other than Noble Gasses) are gases at room temperature?

1. Hydrogen
2. Nitrogen
3. Oxygen
4. Fluorine
5. Chlorine
6. All the above

Answer 1

Hydrogen, nitrogen, oxygen, fluorine, and chlorine are the nonmetals that are gases at room temperature.

Step-by-step explanation:

The nonmetals other than the noble gases that are gases at room temperature are hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), and chlorine (Cl2). These nonmetals exist as diatomic molecules, meaning they are formed by two atoms bonded together. For example, hydrogen gas (H2) is made up of two hydrogen atoms.

The noble gases, which include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn), are also gases at room temperature. Unlike the nonmetals, noble gases exist as single atoms and are called monatomic.
