What is a Lewis Electron Dot Structure?

Back

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

Front

What do the dots represent in a Lewis Dot Structure?

Back

The dots represent the valence electrons of an atom.

Front

How many electrons does each line in a Lewis Dot Structure represent?

Back

Each line represents 2 electrons.

Front

Why do Lewis Dot Structures only show outer-shell electrons?

Back

Only outer-shell electrons can be involved in chemical bonds.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons are the electrons in the outermost shell and are involved in forming bonds with other atoms.
