Atoms have electrons they can share (share a pair of electrons is a covalent bond, which is an extremely stable bond). How many bonds our 6 favorite atoms can engage in? Hydrogen: 1; Carbon: 4; Nitrogen: usually 3 but you can actually get 4; Phospohorus: 5; Sulfur: 6; Oxygen: 2.
We are also trace quantities of ions: Calcium (Ca), Chloride (Cl), Potassium (K), Sodium (Na), Magnesium (Mg), Manganese (Mn) + teeny, teeny weeny bits of Selenium (Se).
