The isotope tin-116.
There are 50 electrons. In a neutral atom, the number of electrons equals the number of protons.
The number of neutrons in an atom can be calculated by subtracting the atomic number (protons) from the atomic mass. In this case, for the isotope of yttrium with an atomic number of 39 and an atomic mass of 89, the number of neutrons is 50 (89 - 39 = 50).
For any element, this is answered in the same way. The mass number is the number of protons plus the number of neutrons, in this case 50. The atomic number is the number of protons. Subtract the atomic number from the mass number to give the number of neutrons. For any element, this is answered in the same way.

Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

All atoms of the specified data contain 38 protons, 38 electrons (assuming they are not ions), and 50 neutrons. They are atoms of the element Strontium.
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.
An atom with atomic number 50 contains 50 protons. The mass number of 125 indicates the total number of protons and neutrons combined, so subtracting the number of protons (50) from the mass number gives 75 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.
Protons = Atomic Number = 50 Neutrons = Atomic Mass - Atomic Number = 125 - 50 = 75
There are 50 electrons. In a neutral atom, the number of electrons equals the number of protons.
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.
The mass number of an atom is the sum of its protons and neutrons. Since tin has an atomic number of 50 (which corresponds to the number of protons), an atom of tin with 70 neutrons would have a mass number of 120 (50 protons + 70 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).
An element with 68-neutrons (n) and 50-protons (p) would have a mass number of 118-atomic mass units (amu). Amu equals the sum of the proton and neutron numbers for any element. In this case atomic number 50 also signifies that it is an atom of tin (Sn).
The atomic number 50 corresponds to the element tin, or Sn.The atomic number tells you the number of protons, which is 50 protons.The mass number is equal to the number of protons + the number of neutrons.So 55 - 50 = 5 neutronsAnd a neutral atom has exactly the same number of protons as electrons, so it has 50 electrons.
The number of neutrons in an atom can be calculated by subtracting the atomic number (protons) from the atomic mass. In this case, for the isotope of yttrium with an atomic number of 39 and an atomic mass of 89, the number of neutrons is 50 (89 - 39 = 50).
