Front

What is electronegativity?

Back

A measure of an atom's ability to attract and hold onto electrons.

Front

What type of bond involves the sharing of electrons between two nonmetals?

Back

Covalent bond.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a nonpolar covalent bond?

Back

A bond where electrons are shared equally between two atoms.

Front

What happens to the electrons in an ionic bond?

Back

One atom donates electrons to another atom.

Front

What is the significance of the periodic table in understanding bonding?

Back

It helps predict the types of bonds that can form based on element properties.
