The element with 99 electrons is einsteinium (Es), which has an atomic number of 99. It is a synthetic element that was first discovered as a result of nuclear tests in 1952.
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.
The Element Neon has 10 protons and 10 electrons.
Oxygen is a non metal element. There are 8 electrons in a single atom.
Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
The element with 6 valence electrons is carbon.
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.
