Mendelevium has 101 protons and electrons.
For each isotope the number of neutrons is different.
Number of neutrons = Mass number of an isotope -101
Sc is a 3d element. It has 21 protons and 21 electrons.

A helium atom has 2 protons, 2 neutrons, and 2 electrons.
Neutrons: 6 Protons: 6 Electrons:6
Mendelevium has 101 protons and electrons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope -101
protons and nuetrons are equal to no. of electrons present in atom
101 electrons...to find the number of electrons in an element, you need to know the number of protons. There are the same amount of protons as electrons. The number of protons is the same number as the atomic number. Mendelevium has 101 as its atomic number therefore 101 protons and therefore 101 electrons.
26 nuetrons, 22 electrons, and 22 protons
20 protons, 20 electrons, and usually 20 neutrons
