How they are formed Valence Electrons Valence Electrons of an atom are the electrons that are in the outermost s and p sub shells ONLY S AND P To determine how many electrons are in your valence shell look at where your element is on the periodic table. The ions are arranged in a lattice. There is attractive electrostatic forces between the ions which are very strong e.g. sodium chloride ionic lattices. .

Complex Ions. Are soluble.. Isotopes. Isotopes. : atoms of the same element that have different numbers of neutrons. Two isotopes of an element will have the same atomic number, but different mass numbers (and atomic masses). CARBON (above right). To write the electron configuration of an ion formed by a main group element:. Write the configuration for the atom.. Add or remove the appropriate number of electrons.. Na: 1. s. 2. 2. s. 2. 2. SNC2D. Polyatomic Ions. Polyatomic ions are groups of atoms that tend to stay together and carry an overall ionic charge. The ion is typically held together with covalent bonds. The polyatomic ion is capable of bonding with other ions. Many ions are monoatomic BUT. Most ions are polyatomic (>1 atom). 330.07.01b.Names & Formulas - Polyatomic.
