What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Back

7

Front

What do metals tend to do with electrons?

Back

Metals tend to lose electrons.

Front

What is an ionic bond?

Back

An ionic bond is formed through the transfer of electrons from one atom to another.

Front

What does a 2+ charge indicate about an atom?

Back

A 2+ charge indicates that the atom has lost 2 electrons.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.

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 polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where electrons are shared unequally between two atoms.
