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
Cadmium-116 has 66 neutrons. This is determined by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons): 116 (atomic mass) - 50 (atomic number) = 66 neutrons.
The isotope of tin-120 has 70 neutrons in its nucleus. Tin, element 50 on the periodic table, typically has 50 protons. By subtracting the atomic number (protons) from the atomic mass (protons + neutrons), we can determine the number of 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.
The element tin, with symbol Sn and atomic number 50, typically has 50 protons. Considering protons + neutrons = atomic mass number, if there were 50 protons and 69 neutrons, the total would be 50 + 69 = 119, which is not the atomic mass of tin (approximately 119).
Indium: 49 protons/electrons, 66 neutronsTin: 50 protons/electrons, 69 neutronsAntimony: 51 protons/electrons, 71 neutrons
there are 66 protons & 97 neutrons
Cadmium-116 has 66 neutrons. This is determined by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons): 116 (atomic mass) - 50 (atomic number) = 66 neutrons.
In-115 isotope has 66 neutrons
50 electrons, 50 protons and 56 neutrons.
The isotope of tin-120 has 70 neutrons in its nucleus. Tin, element 50 on the periodic table, typically has 50 protons. By subtracting the atomic number (protons) from the atomic mass (protons + neutrons), we can determine the number of neutrons.
Cadmium (Cd) - AdadDon1

A zinc atom with a mass number of 66 has 34 neutrons. This is determined by subtracting the atomic number (number of protons) from the mass number, since the mass number represents the sum of protons and neutrons.
All tin isotopes have 50 protons. For neutral atoms, the number of electrons will also be 50. The neutron number is 119 - 50, which is 69.
strontium (which the atomic number is not 85 its 38) has 38 protons and 50 neutrons... hope this helps!
