No, Mendeleev did not know about protons, neutrons, and electrons. He is best known for creating the periodic table of elements based on the properties of the elements without knowledge of the atomic structure. The discovery of protons, neutrons, and electrons came later with the development of atomic theory.
Nitrogen 7 protons, 7 neutrons and 7 electrons Aluminium 13 protons, 14 neutrons and 13 electrons
Positive charge particles are called Protons Negatively charged particles are called Electrons Neutrons have no charge Protons was discovered by Ruther Ford Electrons was discovered by JJ Thompson Neutons was discovered by James Chadwick
