Platinum atom has 78 protons and electrons; the number of neutrons is variable and depends on the Atomic Mass of the isotope (atomic mass of the isotope - atomic number = number of neutrons).
The stable isotopes have 114, 116, 117, 118, or 120 neutrons.
78 protons, 78 electrons and 119 neutrons
78. This is the atomic number of platinum, and any platinum isotope will have this number of electrons per atom.
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
An oxygen atom typically has 8 protons and 8 neutrons in its nucleus.
A Xenon neutron has between 70 to 82 neutrons.
117 neutrons in Pt-195 isotope.
The neutrons are located in the nucleus in any atom.
78 protons, 78 electrons and 119 neutrons
platinum
Each isotope has another number of neutrons.Number of neutrons = Mass number of an isotope – 78
78. This is the atomic number of platinum, and any platinum isotope will have this number of electrons per atom.
A typical atom of iodine contains 74 neutrons.
45 neutrons
A stable atom of Zinc (Zn) typically has 34 neutrons.
The atomic weight minus the number of protons = the atom's neutrons.
52 neutrons.
A typical atom of iodine contains 74 neutrons.
