Explanation:
Element X naturally forms ions with a charge of +1.
Group 1A (alkali metals) forms ions with a +1 charge.
For example, Na
Na tends to lose its outermost electrons and forms Na+1.
Elements in the same group will behave similarly and will form similar compounds
------
We can have NaCl => Na+1 + Cl-1
These elements from group 1 can not gain electrons, they lose their electrons.
If X has a charge of +1, this was because it lost its outermost electron.
Answer: Elements X tends to gain one electron
