How many protons and neutrons doe an atom contain?
Each atom has a unique combination of protons, neutrons, and electrons.
How many neutrons will an atom of platinum contain?
117 neutrons in Pt-195 isotope.
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
If the atomic mass of the atom is 48 and it contains 20 protons, then the atom contains 28 neutrons. This can be calculated by subtracting the number of protons from the atomic mass, since the atomic mass includes both protons and neutrons.
