Americium has 95 protons and electrons. The number of neutrons can vary by isotope, with three notably synthesized: Am-241 (146 neutrons) Am-242 (147 neutrons) Am-243 (148 neutrons).
For isotopes the number of neutrons is different.
Number of neutrons = Mass number of an isotope - 95
The neutral atom of americium has 95 electrons.
Possible valences of americium are between 2 and 7; in the outer shell of electrons americium has 2 electrons.
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
Number of neutrons: atomic mass of an isotope - number of protons Example for Am 241: 241 - 95 = 146

There are 19 known isotopes of americium, with neutron counts ranging from 136 to 154. Americium-241, the easiest to produce, has 146 neutrons. Number of neutrons = Atomic weight (rounded) of an americium isotope - 95 Each isotope has a different number of neutrons. Americium has also 95 protons and electrons.
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.
