1. Many nonmetals are ___ at room temperature. 2. The nonmetals that are solid at room temperature have no ___ . 3. Nonmetals are poor conductors and, therefore, they are good ___ . 4. In group 14, there is only one nonmetal—the element ___

Gases, luster, insulators, carbon are the suitable terms to fill in the gaps.

Explanation:

A nonmetal isan element that does not show the properties of a metal. It can't be made into a wire, pounded into shape or bent, doesn't conduct heat or electricity well, and doesn't have a high melting or boiling point.

The nonmetals are in a minority on the periodic table, mostly located on the right-hand side of the periodic table. The exception is hydrogen, which behaves as a nonmetal at room temperature and pressure and is found on the upper left corner of the periodic table. Under conditions of high pressure, hydrogen is predicted to behave as an alkali metal.

The nonmetals are located on the upper right side of the periodic table. Nonmetals are separated from metals by a line that cuts diagonally through the region of the periodic table containing elements with partially filled p orbitals. The halogens and noble gases are nonmetals, but the nonmetal element group usually consists of the following elements. Therefore, from the question;

1. Many nonmetals are _gases_ at room temperature.

2. The nonmetals that are solid at room temperature have no _luster.

3. Nonmetals are poor conductors and, therefore, they are good _insulators.

4. In group 14, there is only one nonmetal—the element __carbon.

Other general Properties of Nonmetals

Nonmetals have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily. Nonmetals display a wide range of chemical properties and reactivities
