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.
It depends on the isotopes of Americium
e.g. Americium-241 has 95 electrons and 146 neutrons
Americium-243 has 95 electrons and 148 neutrons
To find out the number of neutrons for Americium you take the Isotope number (x) minus away the number of electrons (95)
e.g. Americium-x
So, Americium-x has 95 electrons and (x-95) neutrons..
OR
You take the relative Atomic Mass (x) and subtract it with the number of electrons (95)
(x-95) = Neutrons
Number of neutrons = Atomic mass of the isotope - Atomic number (for Am is 95)
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
The most common isotope, Am-241, has 95 protons and electrons and 146 neutrons.
Americium has 18 isotopes in the range of atomic masses 231 to 249; the number of neutrons is the difference between the atomic mass and the atomic number (for Am is 95).
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons.
Americium has 95 protons.
Depends on the isotope.
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Iron has 26 electrons; the number of neutrons is different for each isotope (number of neutrons = mass number - 26).
Francium has 87 protons and electrons; the number of neutrons is different for each isotope and francium has ca. 40 isotopes ad isomers. Number of neutrons = Atomic mass of the isotope - 87
Beryllium has 4 protons and normally 4 neutrons in its nucleus. It usually has 4 electrons orbiting that nucleus, but this number can change depending on its level of ionisation.
Most atoms of Barium (Ba) have 81 neutrons, but some very rare isotopes have more. The average number of neutrons an atom of Barium has is 81.327, which is its atomic weight (minus the protons).
Tantalum has 73 protons and electrons and its isotopes have 108 or 107 neutrons.
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Thorium 232 has 90 electrons and protons, also 142 neutrons.
Iron has 26 electrons; the number of neutrons is different for each isotope (number of neutrons = mass number - 26).
12 electrons. Remember, electrons and protons must be balanced in charge; neutron number may vary.
Francium has 87 protons and electrons; the number of neutrons is different for each isotope and francium has ca. 40 isotopes ad isomers. Number of neutrons = Atomic mass of the isotope - 87
An atomic nucleus contain protons, neutrons and electrons - not oxygen.
Beryllium has 4 protons and normally 4 neutrons in its nucleus. It usually has 4 electrons orbiting that nucleus, but this number can change depending on its level of ionisation.
11 protons and 10 electrons
The chlorine atom has 17 protons and electrons.
25 electrons.... ( as the number is 25 : being 25 protons and 25 electrons)
proton of fluorine is 9 and neutron is also 9
