Answer:
option B
Explanation:
In Any chemical reaction when an atom gain electrons it become negatively charged ion or cation. For Example oxygen gains 2 electrons and become O-2 ion. And if an atom accept electrons it become positively charged ions for example when magnesium gain 2 electrons it become Mg+2 charged ion.
Atom with negative charge have excess electrons and can lose its electrons while atom with positive charge are deficient in electron so can accept electrons.
