Web17 feb. 2024 · An Einsteinium atom has 99 protons and 99 electrons. And, the number of neutrons in the nucleus of the radioactive metal is 153 (number of protons subtracted from atomic mass). Einsteinium has 17 radioactive isotopes with atomic masses ranging from 241 to 256. However, it has no natural isotopes. It also has three recognized isomers. WebAtomic mass (A) = Nucleus mass = Total mass of protons and neutrons (p + n) Again, the mass of each proton and neutron is about 1amu. Therefore, the total number of protons and neutrons is called the atomic mass number. That is, the number of atomic mass (A) is = p + n grand cru chablis map
