Polonium-210 has 126 neutrons.
Polonium has: 84 protons and 84 electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Po isotope – 84
Depending on the isotope. Number of neutrons = Atomic mass of the isotope - 84
The number of neutrons in an atom can affect the atomic mass of an atom.
Polonium has 84 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - Atomic number of polonium (84)
No, neutrons + protons = mass
The total amount of protons and neutrons in an atom is its mass number.
84 protons, 84 electrons and 136 neutrons.
Mass number!:)
The more stable polonium atoms have 125 neutrons. As with other elements, polonium atoms can have varying numbers of isotopes (variants with different number of neutrons).Polonium has 33 isotopes ranging from 104 to 136 neutrons.
they determine the atomic mass of the atom
the mass number is number of protons in an atom, plus the number of neutrons.
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
