The four most abundant elements by mass in the human body are other nonmetals including oxygen (65%), carbon (18%), hydrogen (10%), and nitrogen (3%). The most abundant of the other nonmetals in the Earth's crust is oxygen which is the single most abundant element in the Earth's crust. Water is made up of the two nonmetals oxygen and hydrogen.

Non- metals are soft, non- malleable and non- ductile substances that can be found in solid, liquid or gaseous state. An alloy is a homogeneous mixture of two or more metals or metals and non- metals. Some of the common examples of metals are copper, brass, silver etc. Some of the common examples of non- metals are carbon, sulphur, phosphorus etc.
