3. a subatomic particle of about the same mass as a proton without a electrical charge and is present in all atoms.
6. the change of energy in a nutral atom when a electron is added to form a negative ion.
11. a negative charged ion

1. The attraction between an electron and nucleus in any atom with more than one electron shell
4. a positive charged ion
5. The measure of the temdancy of an atom to attact a bonding pair of electrons.
7. Any elements that are in the central block of the periodic table.
8. chemical rule that states the atoms of main groups tend to combine in such way that each atom has eight electrons in valance shell, giving it the same electronic structure as a noble gas.
9. The net positive charge experianced by an electron in a multi-electron atom.
