Chemistry

A + BC = AC + B

• One atom gives up an electron to the other, forming positive and negative ions.
• Total charge must be zero.

Two atoms share a pair of electrons, closing the shell for each of them.

• Bond between 2 nonmetals,
• Same electronegativity,
• Equal sharing of the bonding electron pair.

A bond between 2 non-metals that have different electronegativities and have unequal sharing of the electrons.
