Atoms consist of protons, neutrons and electrons
Explanation:
There are three particles in an atom:
- Proton: it is located in the nucleus. Its mass is [tex]m_p = 1.6726\cdot 10^{-27}kg[/tex], and it is positively charged (its electric charge is [tex]+1.6\cdot 10^{-19}C[/tex], also called fundamental charge)
- Neutron: it is also located in the nucleus. Its mass is slightly larger than the proton ([tex]m_n = 1.6749\cdot 10^{-27}kg[/tex]), and it has no electric charge. Protons and neutrons are held together inside the nucleus by the strong nuclear interaction
- Electron: it is located outside the nucleus, in a region called "electron cloud". According to quantum mechanics, its exact position cannot be determined, but it can only be described by a "wave function" which gives the probability of finding the electron at a certain position. Its mass is much smaller than the proton ([tex]m_e = 9.11\cdot 10^{-31} kg[/tex]) and it is negatively charged (its charge is the opposite of that of the proton: [tex]-1.6\cdot 10^{-19}C[/tex]).
