Protons and electrons
Explanation:
The atoms are made up of protons, neutrons, and electrons. The physical and chemical characteristics of an atom are determined by the number of these particle composition. The protons present in the center of an atom called the nucleus is positively charged. The neutrons are also located in the nucleus of an atom with no charge. The electrons has a negative charge and it is placed around the nucleus having different shells and quantum state. The charges of the protons and electrons are denoted by +q and -q . The quantization of these charges are +1, +2, ... and -1, -2, .... etc.
