Solved Examples on Structure of Atom

Atoms are the basic building blocks of matter which has mass and occupies space. They cannot be chemically subdivided by ordinary means. The word ‘atom’ is derived from the Greek word atom which means indivisible. Matter can be broken into small particles called atoms which are too small to be seen through the naked eye.
As discussed earlier, atoms are composed of three types of particles namely protons, neutrons and electrons. A major proportion of mass of an atom is due to protons and neutrons while electrons have very small mass of about (9.108 X 10-28grams).Atoms are the basic unit of matter and it is vital to have a thorough knowledge of its components like electrons, protons and neutrons.
We have enlisted the information of various particles along with their charges in the table given below:
