117 neutrons in Pt-195 isotope.
Each atom has a unique combination of protons, neutrons, and electrons.
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
Each element has a different number of protons and neutrons. So it changes for each element.
It depends it can be protons of neutrons depending on which atom but for many it is neutrons
The atomic weight minus the number of protons = the atom's neutrons.
Each atom has a unique combination of protons, neutrons, and electrons.
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
4 A+
a neon atom has 10 electrons , 10 protons , and 10 neutrons. its mass no. is 20 and atomic no. is 10. it is a stable atom.
An estimated 117 neutrons. This can vary as platinum has different isotopes of different mass thus resulting in varying number of neutrons.
Each isotope has another number of neutrons.Number of neutrons = Mass number of an isotope – 78
A typical atom of iodine contains 74 neutrons.
Each element has a different number of protons and neutrons. So it changes for each element.
11 neutrons
45 neutrons
there are 7 neutrons because when you take away the number of protons, which is 7 as well, from the atomic mass, which is 14 when rounded, you get 7 which is the number of neutrons in nitrogen.
