Answer:
Non-metal
Accepting/Gaining
Explanation:
Ionic bonds are formed when there is complete transfer of electron from one atom to other.
These elements transfer electrons to achieve stable electronic configuration
Metals have low ionisation energy and looses electron easily .Hence metals acquire positive charge.
Non-metals have high electron affinity and accepts electrons easily. Hence non metals gain electron and get a negative charge.
There is strong force of attraction between the opposite charges in ionic bond called electrostatic force.
Examples of ionic compound are : NaCl (Na has +1 charge and Cl has -1)
MgO(Mg has +2 charge and O has -2)
so,
In ionic bonds, the Non-metal becomes negative after Accepting/Gaining electrons
