Ionic and Covalent Bonds

Front

What makes atoms most stable?

Back

Atoms are most stable when their outer shell is complete.

Front

Why do bonds form between atoms?

Back

Bonds form to fill the outermost energy level.

Front

What is more likely for an atom with 3 valence electrons: gain 5 electrons or lose 3?

Back

It is more likely to lose 3 electrons.

Front

What happens to an atom when it loses an electron?

Back

It becomes a positive ion.

Front

How are ionic bonds formed?

Back

Ionic bonds are formed by the transfer of electrons.

Front

What is a covalent bond?

Back

A covalent bond is formed by the sharing of electrons between atoms.

Front

What is a valence electron?

Back

Valence electrons are the electrons in the outermost shell of an atom.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What is the difference between a positive ion and a negative ion?

Back

A positive ion has lost electrons, while a negative ion has gained electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in order to have eight electrons in their valence shell.
