Group 17 Elements Properties Quiz

Bromine is the only element in Group 17 that exists as a liquid at room temperature. The others are gases (fluorine and chlorine) or solids (iodine and astatine).

As you move down Group 17, the elements become less reactive. This is because the outermost electron is farther from the nucleus and is less attracted to it, making it easier to remove.

Group 17 elements are known as halogens. Halogens are highly reactive nonmetals. They form ionic compounds with metals, where the halogen gains an electron to form a negative ion.

Group 17 elements, also known as halogens, are very reactive nonmetals that readily form covalent compounds with other nonmetals. They share electrons to achieve a stable octet configuration.

The state of matter for Group 17 elements gradually changes from gaseous (fluorine and chlorine) to liquid (bromine) to solid (iodine and astatine) as you move down the group. This happens because the atomic size increases, leading to stronger intermolecular forces.
