ANSWER alkali metal

Answer 2

Alkali metals = have one valance electron

Alkaline earth metals = have two valance electrons

Transition metals = Group 3- 12.

Halogens = have seven valance electrons

Includes fluorine, chlorine, bromine, iodine, and iodine.

Noble gases = Other than He have 8 valance electrons.

Step-by-step explanation:

Alkali metals = have one valance electron

Alkali metals are present in group one. All alkali metals have one valance electron.

Alkaline earth metals = have two valance electrons

Alkaline earth metals are present in group two. All alkaline earth metals have two valance electrons.

Transition metals = Group 3- 12.

Transition metals are present in middle of periodic table. Transition elements are present in group 3-12.

Halogens = have seven valance electrons

Halogens are present in group seventeen. All halogens have seven valance electrons. Halogens elements ,

Includes fluorine, chlorine, bromine, iodine, and iodine.

Noble gases = Other than He have 8 valance electrons.

Noble gases are present in group eighteen. All noble gases are inert.
