The three subatomic particles in the atom are protons, neutrons and electrons
Explanation:
There are three subatomic particles in the atom:
- Proton: the proton is positively charged, and its electric charge is [tex]q=+1.6\cdot 10^{-19}C[/tex]. Its mass is [tex]m_p = 1.67\cdot 10^{-27} kg[/tex]. The proton is found in the nucleus of the atom. In reality, the proton is not a fundamental particle, since it consists of three quarks.
- Neutron: the neutron is also found in the nucleus. It has no electric charge, and its mass is slightly larger than that of the proton. Neutrons are responsible for holding the nucleus of the atom together: in fact, the protons tend to repel each other due to the electrostatic repulsion; however, neutrons and protons exert on each other the strong nuclear force, which is attractive and keep them together, preventing the nucleus from breaking apart. The neutron is also made of three quarks.
- Electron: the electron has a negatively charge, [tex]q=-1.6\cdot 10^{-19} C[/tex], and its mass is much smaller than that of protons and neutrons [tex](m=9.11\cdot 10^{-31} kg[/tex]). The electron is not in the nucleus, but it is found in orbitals around the nucleus. The electron is a fundamental particle.
