Atomic Number Quizzes & Trivia

An atom is a primary piece of matter which is made up of protons, neutrons, and electron called subatomic particles. The centre of the atom is known as Nucleus, around which electrons flow which carries the negative charge. This quiz has been developed to test your knowledge about atomic numbers, protons, atomic mass and neutrons. So, let's try out the quiz. All the best!
