This is SODIUM chloride, also known as table salt. Most people scientist know that the formula for salt is NaCl. One sodium (Na) atom gives it's electron to one chlorine (Cl) atom. Chlorine then has the eight electrons in its outer shell to make it "happy". Sodium is "happy" because it has now given up its one extra electron.
