Electron dot structures
An atom or group of atoms that have a net electric charge.
An atom that has lost an electron. Typically metals.
An atom that has gained electrons. Halogens.
Negative ion (anion)
Show the charges on an ion.
Atoms gain or lose electrons until their valence shell is filled to capacity.
How many valence electrons do atoms want?
The region where an atom's valence electrons are located. These are the electrons available for taking part in chemical reactions.
A bond between two oppositely charged ions created by electric charges.
A compound created by ions. (2NaCl)
An ion composed of more than one atom. NO-3
A chemical bond between atoms that share electrons.
