1. what is polarity?
a. an ionic bond with unequal electrons
b. an ionic bond with equal electrons
c. a molecule with equal electrons
d. a molecule with unequal electrons

Polarity is an ionic bond with unequal electrons

Option A

Explanation:

In polar covalent bonds, the atoms possess an uneven attraction of electrons, which causes an uneven sharing. This sometimes simply called the polar bond, the electron distributions around the molecule are asymmetrical. As the electronegativity variation higher, the resonance increasingly supports the contribution of ions.

If the difference in electronegativity is very large, for example between the electropositive atoms like sodium and electronegative atom such as fluorine, resonance dominates in the ionic structure, and the bond can be considered ionic. As the electronegativity variation between the two bound elements increases, the non-polar bond becomes a polar bond, which then becomes as an ionic bonds.

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.
