Front

What is a Lewis structure?

Back

A Lewis structure is a diagram that shows the bonding between atoms and the lone pairs of electrons in a molecule.

Front

What is the octet rule?

Back

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

Front

How do you determine the total number of valence electrons in a molecule?

Back

Add the valence electrons of each atom in the molecule, considering any charges.

Front

What is a single bond in terms of electron sharing?

Back

A single bond involves one pair of shared electrons.

Front

What is a double bond in terms of electron sharing?

Back
