Which of the following are characteristics of nonmetals?Group of answer choicesconduct electricitydullbrittlemany are gasesall of them are solidsdo NOT conduct electricityshiny

The characteristics of nonmetals include:

1. Many are gases: Nonmetals can exist in various states, but many of them, such as hydrogen, oxygen, nitrogen, and the noble gases, are gaseous at room temperature.

2. Brittle: Nonmetals that are solid at room temperature, like sulfur and phosphorus, are generally brittle. This means they are likely to break or shatter when subjected to stress or pressure.

3. Dull: Nonmetals do not have a shiny or lustrous appearance. Instead, they are usually dull.

4. Do NOT conduct electricity: Nonmetals are poor conductors of electricity. This is because they do not have free electrons that can move and carry an electric charge.

The characteristics that are NOT typical of nonmetals include:

1. Conduct electricity: As mentioned above, nonmetals are generally poor conductors of electricity.

2. All of them are solids: This is not true as many nonmetals are gases at room temperature, and Bromine is a liquid.

3. Shiny: Nonmetals do not have a shiny or lustrous appearance. They are generally dull.
