The atomic nucleus was discovered by Ernest Rutherford in 1911. In 1913, it was proven that the charge of the nucleus was equal to its atomic number. In 1919, Rutherford proved that the nuclei of all atoms contained particles described as hydrogen nuclei, and this is considered the discovery of the proton.
Elements with 133 protons or 197 protons have not been discovered or named so far.
Binomial particles like protons, neutrons, and electrons were discovered by multiple scientists. The electron was discovered by J.J. Thomson in 1897, the proton was discovered by Ernest Rutherford in 1919, and the neutron was discovered by James Chadwick in 1932.
No, Dmitri Mendeleev did not know about protons. The concept of protons was not discovered until later in the 20th century, after Mendeleev's time. Mendeleev is most famous for creating the periodic table of elements.
Ernest Rutherford and James Chadwick were the scientists who discovered the subatomic particles that make up the nucleus. Rutherford discovered the positively charged protons, while Chadwick discovered the uncharged neutrons.
Scientists have accepted that the nucleus of the atom consists of neutrons and protons since the early 20th century, around the 1920s. This understanding was developed through experiments by scientists like Ernest Rutherford and James Chadwick.

Protons were discovered when the nucleus of atoms were discovered. Electrons were already known about, so when the nucleus was discovered, it was known that it had to contain positively charged particles: protons. The nucleus was discovered by Ernest Rutherford by shooting alpha particles (helium nuclei, basically helium without the electrons) at a thin sheet of gold. Most of the alpha particles went straight through, but some if them were scattered. Rutherford deduced that these particles had hit something in the foil that didn't take up a large percentage of space: the nuclei of the gold atoms.
There 38 protons in strontium. Strontium is No. 38 in the Periodic Table.. This indicates the number of protons and electrons in a neutral atom of strontium . Strontium is named after the Scottish village, Strontian, in the Highlands of Scotland, where it was first discovered.
Cerium was discovered in 1803 Cerium--- Ce atomic number--- 58 atomic mass--- 140.116 # of protons--=58 # of neutrons--- 82 # of electrons---58
Rutherford discovered that almost entire mass of an atom is located in the nucleus, and then, the neutron was discovered by Chadwick.
