Front

What is a Lewis structure?

Back

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

Front

What does a dot diagram represent?

Back

A dot diagram represents the valence electrons of an atom using dots around the element's symbol.

Front

How do you determine the number of valence electrons for an element?

Back

The number of valence electrons can be determined from the element's group number in the periodic table.
