The atoms constitute electrons, neutrons, and protons. The nonmetal atom accepts the electron to complete its octet and becomes a negative ion. Thus, option B is correct.
What are non-metals?
Non-metals are the group of the periodic table that are marked as the elements with poor conductivity and non-malleability. They are easy to break and not lustrous.
In a chemical reaction between a metal and non-metal the nonmetal tends to form an anion by accepting the electron and becomes negative in charge.
The tendency of the non-metal to gain an electron to complete its octet or the outer shell of the atom results in higher electronegativities than the metals.
Therefore, in option B. the non-metals accepts electron and becomes negative in charge.
