Binary+Ionic

__**Positive Ions**__ (cations) Na+ = sodium ion Zn = zinc ion
 * Examples:**
 * If an element can form more than one (1) positive ion, the charge is indicated by the Roman numeral in parentheses followed by the word "ion"


 * Examples:**
 * Fe2+ = iron(II) ion
 * Fe3+ = iron (III) ion

> > **Examples:** > > || ClO- = hypochlorite || > > **Example:** > CO32- becomes HCO3- > "Carbonate" becomes either "Hydrogen Carbonate" or "Bicarbonate" > > **Examples:** >> sodium + chloride --> sodium chloride >> copper(II) + sulfate --> copper(II) sulfate >> aluminum + nitrate --> aluminum nitrate
 * __ Negative Ions __** (anions)
 * 1) Monatomic anions (a single atom with a negative charge) change their ending to "-ide"
 * O2- = oxide
 * Cl- = chloride
 * 1) Oxyanions (negatively charged polyatomic ions which contain O) end in "-ate". However, if there is more than one oxyanion for a specific element then the endings are:
 * Two less oxygen than the most common starts with "hypo-" and ends with "-ite" || One less oxygen than the most common ends with "-ite" || **====THE MOST COMMON OXYANION ENDS WITH "-ATE"====
 * || One more oxygen than the most common starts with "per-" and ends with "-ate"< ||
 * ClO2- = chlorite
 * NO2- = nitrite
 * SO32- = sulfite
 * || Most common oxyanions with four oxygens
 * SO42- = sulfate
 * PO43- = phosphate
 * CrO42- = chromate || Most common oxyanions with three oxygens
 * NO3- = nitrate
 * ClO3- = chlorate
 * CO32- = carbonate || || ClO4- = perchlorate ||
 * 1) Polyatomic anions (a negatively charged ion containing more than one type of element) often add a hydrogen atom; in this case, the anion's name either adds "hydrogen-" or "bi-" to the beginning
 * 1) When combining cations and anions into an ionic compound, you always put the cation name first and then the anion name (the molecules are also written in that order as well.)
 * Na+ + Cl- --> NaCl
 * Cu2+ + SO42- -->CuSO4
 * Al3+ + NO3- --> Al(NO3)3
