What does a row in the periodic table represent ?

• A group in the periodic table.

• An element in the periodic table.

• A block in the periodic table.

• A period in the periodic table.

Which answer best describes the attributes of non-metals?

• Non-metals are excellent conductors of electricity.

• Non-metals have low electronegativities and are always gases.

• Non-metals are typically found only in solid form.

• Non-metals are generally poor conductors, have high electronegativities, and can exist in various states. Most are gases, and solid non-metals are brittle
