Molecule of an element is defined as the aggregate of atoms of similar elements. Example: . Molecule of a compound is the aggregate of atoms of different elements in a fixed ratio by mass. Example:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example:
A pure substance is a substance which contains definite composition of only one type of component. Hence, it cannot be separated by physical means. Example: Helium, water
It has a trigonal planar structure. So, the calculated angle is 127.3 degrees.
