What has 50 protons and 66 neutrons?

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.


What has 50 protons with 116 mass number?

The element with 50 protons and a mass number of 116 is tin (Sn).


If a atom of tin has a mass of 118 and an atomic number of 50 how many electrons does it have?

If the atomic number is 50, the number of electrons is 50.


How many protons electrons and neutrons does an atom with atomic number 50 and mass 125 contain?

Protons = Atomic Number = 50 Neutrons = Atomic Mass - Atomic Number = 125 - 50 = 75
