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.
The element with 99 protons is Einsteinium, with the chemical symbol Es. It is a synthetic element named after physicist Albert Einstein. Einsteinium is not found naturally and is produced in nuclear reactors or particle accelerators.
Einsteinium. No joke. Symbol is "Es". Named after Albert Einstein.

The chemical element of chlorine has 18 nuetrons,17 protons and 17 electrons
Einsteinium is a radioactive element that is man-made and does not occur naturally in the environment. It is a synthetic element with no known biological function.
This is 100% dependant on the element and the isotope of the element. Not every nucleus is the same.
The element einsteinium was discovered in December 1952 by Albert Ghiorso and co-workers.
Einsteinium is an element, not a mixture or compound. It is a synthetic element with the atomic number 99 and is named after Albert Einstein.
Einsteinium is not extracted from the earth, it is an artificial element.
