Einsteinium. No joke. Symbol is "Es". Named after Albert Einstein.
It is the synthetic trans-uranium element californiumthat has atomic number 98.
Einsteinum, I assume you mean the Atomic Number.
einsteinium, symbol: Es. I'm posting a link to an online Periodic Table on Webelements.com
Einsteinium has the atomic number 99.

The atomic number is the number of protons in an atom of an element.
Atomic number = Number of protons
The atomic number of the element americium (Am) is 95. From this we can tell that the nucleus of the atom is 95 protons. As an atom is electrically neutral (number of positively charged protons is equal to the number of negatively charged electrons and both carry a relative charge of magnitude 1), an americium atom would also have a total of 95 electrons in its electron shells. The mass number of Am is likely around 243, so you can estimate that an atom of Am would have 243 - 95 = 148 neutrons. Of course, if there are isotopes, the number of neutrons would vary for each isotope of americium.
The element Europeum, symbol Eu, atomic number 63, is named after Europe. The element Americium, symbol Am, atomic number 95, is named after America.
Americium, with the chemical symbol Am, is the chemical element with the atomic number 95.
See the link bellow - chemical elements from atomic number 95 to atomic number 118.
Americium - atomic number 95
#93 Neptunium See also the periodic table at the link below.
Am stands for Americium. It's a radioactive element. It is created in a laboratory and is not natural. It has an atomic weight of 243 and it's atomic number is 95. It has 95 protons, 95 electrons, and 148 neutrons.

Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
An element's atomic number is the # of protons in its nucleus.
