Two atoms of the same element with different atomic masses.
Bond between elements where the electronegativity difference is less than 2.0- the atoms do not share electrons equally.
The seven horizontal rows in the periodic table
A physical combination of two or more substances where each substance maintains its own chemical properties.
A negatively charged ion
An atom or covalently-bonded molecule with an overall charge. These can form ionic bonds with others of opposite charge

Without a crystalline structure
The electrical energy present in an atomic particle. Usually categorized as positive or negative and, for an ion, is equal to the difference between the number of protons and the n
Negatively-charged particles in the outer-most electron shell of an atom
The minimum amount of energy required to completely remove an electron from a gaseous atom or ion
Bond between elements where the electronegativity difference is less than 2.0- the atoms share electrons equally.

Bond between elements where the electronegativity difference is less than 2.0.- the atoms share electrons either equally or somewhat unequally.
Bond between elements where the electronegativity difference is 2.0 or greater- one atom takes the other’s electrons.
