Elements and Chemical Bonds

Dots in a Lewis dot diagram represent

An ion is an atom that has gained or lost

In a compound where the electrons in the bonds are unequally shared it makes the molecule

The energy levels of an atom are occupied by

What is the group number for the elements that have a stable number of electrons?

How many electrons are needed in the outer energy levels of most atoms for the atom to be chemically stable?

Atoms that gain electrons become ions with what charge?

positively charged center that contains most of the mass of the atom

positive ion and negative ion joined together
