Summary Introduction
To describe: The properties of three subatomic particles of atoms.
Introduction: The atoms are formed from their subatomic particles. These particles construct the structure of an atom and provide it its distinctive properties. The molecules present in the body of living organisms are known as biological molecules which are formed from the combination of a number of atoms.

In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)arrow_forward
