Document Summary
Ions are particles that particles that have gained electrons. If combined - left wing loses electrons and the right wing gains them. Molecular share investable electrons on the outer shell making molecules. Molecules come from both right wing (wal street corporation example) Hydrogen is an exception nh4 makes an ionic bond but other hydrogen bonds are molecular. Ionic formulas must become neutral called an empirical formula. Top number is proton count on periodic table add the top left number to the proton to get electron count add protons to neutrons to get the top left number. Sulfur goes to sulfide when bonded with a cation. To find charge of cation, find the charge or the anion first and determine the charge of the cation by what number makes the anion neutral mn2o7 o7=-14 so mn2=+14 manganese(vii)oxide. If a chemical formula starts with an h its an acid.
