Moving through the elements in That gives the # of outer shell electrons. Explanation: Understanding valence electrons is key to understanding chemical bonding. His discovery of alpha and beta rays are important to chemistry because that is the foundation of radioactive decay. Each shell can hold a maximum number of electrons. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. They follow a standard notation in which all electron-containing atomic subshells are placed in a sequence. Valence electrons are those electrons farthest away from the nucleus of an atom. Similarly, magnesium (Mg) and aluminium (Al) have their valency as two and three, respectively as they have two and three electrons in their outermost shell.
