These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number. Protons and neutrons contribute nearly all of an atomâs mass; the number of protons and neutrons is an elementâs mass number.
Building Blocks of The Earthâs Crust. Silicates are the most widespread of the minerals.

By themselves they make up over 90% of the weight of the earthâs crust.Most rocks are composed mainly of this class of minerals.ilicates are the most widespread of the minerals.
