WebChemists observe patterns in different properties of elements as they are arranged in the periodic table. Covalent radius The covalent radius (a measure of how large individual atoms are) shows... WebReactivity is a measure of how easily an element will combine with other elements to form compounds. Some elements are unreactive and need energy putting in others will react spontaneously and easily. The size of the nucleus determines the chemical reactivity of the element due to its ability to hold onto electrons and attract electrons.
