Phosphorus is a vital plant nutrient and its main use - via phosphate compounds - is in the production of fertilizers. Why is the covalent radius of sulfur smaller than phosphorus? For example, the atomic-ionic radius of chlorine (Cl-) is larger than its atomic radius. This means that electron releasing tendency of ammonia is also more and is therefore, a stronger base than phosphine. The ionization potential of an element is the amount of energy required to remove an electron from an isolated atom or molecule. Atomic radius can be defined as a measure of the size (distance) of the atom of a chemical element such as hydrogen, oxygen, carbon, nitrogen etc, typically from the nucleus to the valence electrons.
