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 Lewis dot structure?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What is the octet rule?

Back

The principle that atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What is an ionic bond?

Back

A chemical bond formed between two ions with opposite charges.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms.
