Question

highly reactive metals :Alkaline metals :: highly reactive non metals: ​

Answer 1

Answer:

halogens

Explanation:

Elements in group 17 are called halogens . They are highly reactive nonmetals with seven valence electrons. The halogens react violently with alkali metals, which have one valence electron. The two elements combine to form a salt

Answer 2

Answer:

The alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs),and francium (Fr). This group lies in the s-block of the periodic table, as all alkali metals have their outermost electron in an s-orbital.

Alkaline metals are Magnesium, Calcium, Sodium, Potassium, Strontium,Lithium , Beryllium, Caesium , Barium , Radium , Rubidium

The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the periodic table, and the halogens are the most reactive...
