Einsteinium has 99 protons.
Einsteinium has 99 protons and electrons.
Because einsteinium has 99 protons he has also an identical number of electrons.
There are 99 protons.
Einsteinium has 153 neutrons, 99 protons, and 99 electrons. It's atomic mass is 252 and its shells are 2, 8, 18, 32, 29, 8, 2. Its chemical symbol is Es. Einsteinium has 19 isotopes; each isotope has a different number of neutrons.
Einsteinium is composed from neutrons, protons an electrons - as all other elements.
As all other chemical elements einsteinium contain protons, neutrons and electrons.
Thorium. It's atomic number is 90, so it has 90 protons
Einsteinium has 99 protons and 99 electrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element Einsteinium's atomic number is 99 but Es has 19 known isotopes.
Einsteinium has 99 protons and electrons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 99
99 protons 99 electrons Number of neutrons = Atomic mass of an isotope - Atomic number of the element Einsteinium's atomic number is 99 but Es has 19 known isotopes.Einsteinium has 99 protons.
Because einsteinium has 99 protons and electrons and his position in the periodic table of Mendeleev is consequently 99.
Einsteinium has 7 electron shells.
