Question

Among the following the monovalent positive ions are A)Pottasium B)Magnesium C)Rubidium D)Barium​

Answer 1

Explanation:

Among the following the monovalent positive ions are

A)Pottasium ✔

B)Magnesium

C)Rubidium ✔

D)Barium

Explaination :-

Potassium and Rubidium has 1 valence electrons in their outermost orbit and if they lose 1 electron then they gains inert gas configuration, which make them stable. and they are losing 1 electron it means, 1 positive charge appear on that atom.

Hence,

Potassium (K) and Rubidium (Rb) has monovalent positive ions.

Answer 2

Answer:

option A and c

Explanation:

because their valency is 1
