Which equation shows the process that takes place when X forms ions?
X'
A X + e
X X
B X
→ X
сх

DX-e → X

Answer 1

Element X in Group I of the Periodic Table forms ions by losing one valence electron.

Step-by-step explanation:

Element X is in Group I of the Periodic Table. Group I elements, also known as alkali metals, have one valence electron. To form ions, the alkali metals lose their valence electron, which results in a positively charged ion. The equation that shows the process when X forms ions is:

X → X+ + e-
