The element is Tin. This can be worked out by simply finding the element with the proton number (or atomic number) of 50. You can double check this by working out the Atomic Mass number by adding 50 + 66 to give 116.
The atomic mass number may not always be the same with elements (as seen with this example) because what you're referring to is an isotope.
An isotope is an atom of the same element with the same number of protons but a different number of neutrons. Often 1-4 numbers off its original atomic mass number.
Indium: 49 protons/electrons, 66 neutronsTin: 50 protons/electrons, 69 neutronsAntimony: 51 protons/electrons, 71 neutrons
120(protons + neutrons) - 50(protons) = 70 neutrons
If its a neutral atom, there will be the same number of protons as electrons. The atomic number will tell you how many protons there are, so there are 50 protons and 50 electrons.The mass number is the sum of the number of protons (or electrons in a neutral atom) and the number of neutrons. Since we know there are 50 protons, we subtract 125 with 50 to get 75 neutrons.
Yes!
For the commonest isotope there are 42 protons , 42 electrons and 56 neutrons. However, it has several naturally stable isotopes, they have, 50 neutrons, 52 neutrons, 53 neutrons, 54 neutrons, 55 neutrons and 58 neutrons. However, for all isotopes the number of protons and electrons remains the same, otherwise it would be a different element.
there are 66 protons & 97 neutrons
Indium: 49 protons/electrons, 66 neutronsTin: 50 protons/electrons, 69 neutronsAntimony: 51 protons/electrons, 71 neutrons
In-115 isotope has 66 neutrons
50 electrons, 50 protons and 56 neutrons.
120(protons + neutrons) - 50(protons) = 70 neutrons
Cadmium (Cd) - AdadDon1

Protons = Atomic Number = 50 Neutrons = Atomic Mass - Atomic Number = 125 - 50 = 75
strontium (which the atomic number is not 85 its 38) has 38 protons and 50 neutrons... hope this helps!
Yes!
Osmium, if you take the Atomic Mass (190.2) and subtract the Atomic number (76), you get the result of 114, this is the number of protons, not the protons and neutrons combined.
I don't know Se-50.
