Question

X is an atom of an element taht has 20 electrons . if X forms an ion by losing 2 electrons
a) what will be the charge on the ion
b)what will be the number of protons in the ion
c)X combines with Cl to form XCl2 . what is the valency of X and Cl?
d) X forms a carbonate . write the chemical formula of X carbonate with suitable steps

anyone who answers correctly will be marked branliest

Answer 1

Answer:

A- Charge of the ion will be +2.

B-The number of protons will be 20 and it will not change.

C -The valency of X is +2, and Cl is -1.

D- The chemical formula of the carbonate will be XCO3 .

X has 2 electrons in its valence shell ,so it will donate them to form +2 ion,and carbonate ion will accept those two donated electrons to obtain -2 charge.
