Front

In a polar covalent bond, electrons are shared ___________.

Back

unequally

Front

How many electrons are represented by a single straight line in a Lewis structure?

Back

Front

This is an example of a __________ bond.

Back

Front

Partial charges like the ones shown here are called:

Back

Front

What is bond polarity?

Back

Bond polarity refers to the distribution of electrical charge over the atoms joined by the bond.

Front

What type of bond is formed between two non-metals with similar electronegativities?

Back

Non-polar covalent bond.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What is a dipole moment?

Back

A dipole moment is a measure of the separation of positive and negative charges in a molecule.

Front

What is the difference between polar and non-polar molecules?

Back

Polar molecules have a net dipole moment due to unequal sharing of electrons, while non-polar molecules do not.
