Document Summary

When atoms or molecules lose or gain elections, they form charged particles called ions: na na+ e, o + 2e- o2- No change in protons when an ion forms only electrons. Most molecules and atoms are happy with the number of electrons they have. Ions are molecules or atoms that are extra greedy/generous with electrons. They have a positive or negative charge as they give up or take an extra electron or two. Ions that correct electricity with contact with water. Oxoanions nitrogen, sulfur and chlorine with a ton of oxygen. Swap the superscripts to the opposite subscripts and absolute value then simplify! First word is usually a metal, second word/element is usually a nonmetal. Cations name same as the element name. Monatomic anions add ide to name after first syllable. Remember the balance the charge when writing out the formulas. Unlike ionic compounds, there is no simple way to deduce the.
