Lydia Elliott · Answer 1

Antimony - metalloid

Tungsten - Transition metal

Argon - Noble gas

Iron - Transition metal

Bromine - Halogen

Cesium - Alkali metal

Cerium - lanthanide

Uranium - Actinide

Calcium - Alkaline earth metal

Lithium - Alkaline metal

Explanation:

Lithium is an alkaline metal because it belongs to group 1 of the periodic table. This is the general name for the group.

Calcium is an alkaline earth metal as it belongs to group 2 of the periodic table. This is the general name of the group.

Uranium is an actinide as it belongs to the second series of the f block

Cerium is the second element in the lanthanide series after lanthanum

Cesium belongs to group 1 and hence is an alkaline metal.

Bromine is a halogen as it belongs to group 7 of the periodic table

Iron is a transition metal as it belongs to the first series of transition metals

Argon is s noble gas as it belongs to group 18

Tungsten is s transition element and it belongs to the third series

Antimony is a metalloid
