The mass number of Am-241 is 241; each isotope has another mass number.
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
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 valences between 2 and 7.
The most known isotopes of americium are 241Am and 242Am.
americium-243
Mass number = Number of protons + Number of neutrons For the isotope 241Am the mass number is 241; for 242Am is 242, for 243Am is 243, etc. Americium has isotopes with mass numbers that range from 231 through 249.
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.
The atomic mass of the isotope americium-242 is 242,059 549 2.
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 can be explosive only in the situation when the critical mass is reached; but because americium is scarce and this mass is great this situation was impossible until today.
Americium has (all the isotopes) 95 electrons.
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
The atomic number of americium (Am) is 95.
The atomic number of americium is 95.
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.
