#20
Front (Question)

Electronegativity

Back (Answer)

Measure of relative attraction that an atom has for the shared electron in a bond. Determined by nuclear charge and number of other electrons present in electron shell.

#21
Front (Question)

Bond Polarity

Back (Answer)

Measure of the degree of inequality in the sharing of electrons in a chemical bond.

#22
Front (Question)

Nonpolar Covalent Bond

Back (Answer)

Covalent bond in which there is equal sharing of electrons between two atoms.

#23
Front (Question)

Polar Covalent Bond

Back (Answer)

Covalent bond in which there is unequal sharing of electrons between two atoms.

#24
Front (Question)

Trait of Polar Covalent Bonds

Back (Answer)

The greater the difference in electronegativity, the more polar is the bond.
