Mendelevium is element 101, so it has 101 protons. Several isotopes are known, with atomic masses ranging from 245 to 262, hence from 144 to 161 neutrons. The most stable, with half-lives measured in weeks rather than hours or less, have Atomic Mass 258 and 260, thus 157 and 159 neutrons.

Mendelevium has 101 protons and electrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of Md is 101, but Md has 15 isotopes each having another number of neutrons.
