Which type of compound is most likely to be a gas at room temperature?

covalent compounds
Elements that are gases at room temperature are all nonmetals (such as He, Ar, N2, O2, and so on). Compounds that are gases at room temperature are all covalent compounds (such as CO2, SO2, and NH3) that contain two or more nonmetals. With only rare exception, these gases have relatively small molecular weights.

Which elements are a gas at room temperature?

Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).

Which kind of bond produces compounds that are mostly liquids gases at room temp?

Covalent Bonds vs Ionic Bonds

Which of the compounds is likely to be a solid at room temperature?

Ionic compounds typically are solids at room temperature. They form a crystal lattice structure when more than one molecule is present (see Figure A). Notice that the positive charges and negative charges alternate.

Which diatomic molecules are not gases at room temperature?

Of these, all except the noble gases exist as diatomic molecules. Only two elements exist as liquids at a normal room temperature of 20°C–25°C: mercury and bromine.

What elements are gases at ordinary conditions?

The gaseous element group; hydrogen (H), nitogen (N), oxygen (O), fluorine (F), chlorine (Cl) and noble gases helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) are gases at standard temperature and pressure (STP).

Which one of the gas has lowest temperature?

Many gases are liquid at these low temperatures. They can be colder, but the following list is the temperature at which these gases boil….Questions and Answers.

Which elements are not gases at room temperature?

Eleven non-metals are gases at room temperature, including oxygen and chlorine. One non-metal, bromine, is a liquid at room temperature. The other non-metals are solids at room temperature, including carbon and sulfur….Diamond and graphite.

Why compounds with weak molecular forces are usually gases?

Intermolecular forces are much weaker than the strong covalent bonds within the molecules. Very little energy is needed to overcome the intermolecular forces, so simple molecular substances usually have low melting and boiling points. They are often liquids or gases at room temperature.

Why are molecular covalent substances are often gases?

Properties of simple molecular substances All have strong covalent bonds between their atoms, but much weaker intermolecular forces between molecules. At room temperature, simple molecular substances are gases, or liquids or solids with low melting and boiling points.

Are molecular compounds solid liquid or gas?
