95 electrons, two of them are in the outer orbit.
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons.
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
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.

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).
Americium has 95 electrons.
Americium can have 2, 3, 4, 5 or 6 valence electrons
Americium's atomic number is 95. Therefore, it has 95 protons per atom, all of which have a +1 charge. For it to be electrically neutral then, americium must also have 95 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.
1. Radium has 88 protons. 2. Radium has not... americium !
The sum of protons and neutrons in an americium atom is determined by its atomic mass number, which is around 243. Americium typically has 95 protons and thus 95 electrons in a neutral atom, as the number of protons and electrons are equal in a neutral atom. Therefore, the sum of protons and neutrons in an americium atom is approximately 243 in most naturally occurring isotopes.
