Technetium has the atomic number 43 but is an isotope with 99 protons
It has 43 protons 43 neutrons and 43 electrons.
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 (all the isotopes) 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.
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.
It has 43 protons 43 neutrons and 43 electrons.
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
Tc has 55 neutrons, its variants such as Tc-99 have a differing number of neutrons ranging from 54, 55, and 56 in the longer lived isotopes such as Tc-99. Tc-99 also has a half-life of 211,000 years.
In a neutral atom of 243Am (Americium), there are 95 protons (which corresponds to its atomic number), approximately 148 neutrons (which can be calculated by subtracting the atomic number from the atomic mass), and 95 electrons (equal to the number of protons in a neutral atom).

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-241 has: 95 protons, 95 electrons, 146 neutrons.For other isotopes the number of neutrons is different.Number of neutrons = Mass number of an isotope - 95
