39 for each
Yttrium's atomic number is 39, meaning that it always has 39 protons in its nucleus. This is, in fact, all that we know for sure about yttrium unless we are given the mass number, which is the total number of protons and neutrons in its nucleus, of a specific yttrium isotope. Thirty-two different yttrium isotopes, ranging in mass number from 77 to 108, have either been found or synthetically produced. Therefore, the number of neutrons in an yttrium atom could be anywhere from 38 to 69. Yttrium's only stable isotope, 89Y, has 50 neutrons.
Yttrium has 39 protons and 50 neutrons.It is represented by symbol Y.It belongs to group 3 of transition metals.

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).
Look at the atomic number. That will be the number of protons and electrons; subtract that number from the atomic mass (rounding down) and you'll have the number of neutrons.
Yttrium has 50 neutrons. To find the number of neutrons, subtract the atomic number (39) from the atomic mass (89): 89 - 39 = 50 neutrons.
The transition metal with 39 protons is Yttrium (Y), which has chemical symbol Y and atomic number 39.
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons
Number of protons + Number of neutrons = Mass number(number of nucleons)
Mass number is about the neutrons and protons. The total of neutrons and protons.
The number of protons is equal ti the number of electrons. Yttrium is the element. It is in the d block.
An atom with 17 protons and 20 neutrons would be chlorine-37, which has a total atomic mass of 37 (17 protons + 20 neutrons).
