What is inside an atom of element?
Every element is made up of atoms. An atom of a combined element is called molecule. Inside the atom there are 3 particles ------
1. Proton
2. Neutron
3. Electron
Proton is having positive energy. Electron is having negative energy. Neutron is not having any charge , we can call it as neutral.
The centre of atom is nucleus. In nucleus , we find protons and neutrons. Electrons are not inside nucleus. They revolve around the nucleus.
The atomic number of an element is denoted by the number of electrons it is having in atom. The weight of protons and neutrons are comparatively similar and sum is denoted by atomic number of element. The number of protons determines its chemical element and the number of neutrons, the isotope of element. The electrons are bound to nucleus by electro magnetic force.
