39 for each
The stable isotope of YTTRIUM (Y-89) has 50 neutrons. It has 39 protons and 39 electrons also as its atomic number is 39.
Yttrium has 39 protons.
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.
Protons: 39 Neutrons: 50 Electrons: 39
The element yttrium (Y) has 39 protons.
The number of protons is equal ti the number of electrons. Yttrium is the element. It is in the d block.
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.
50 because 89(the atomic number, which is the amount of protons+the amount of neutrons)-39(the amount of protons) is 50
Yttrium's atomic number is 39. Thus, to be neutral, it must have 39 protons and 39 electrons. Yttrium's stable isotope is 89Y, which has 89 - 39 = 50 neutrons.
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
Atomic mass = number of protons + number of neutrons Mass number = number of protons + number of neutrons
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons
It has the same number of protons and electrons. It has none to about 2x the number of neutrons as protons, depending on the number of protons (more protons, more neutrons).
Mass number = number of protons + number of neutrons
Mass number = Number of protons + Number of neutrons
Mass number is about the neutrons and protons. The total of neutrons and protons.
Mass number = Number of protons + number of neutrons. Atomic number = Number of protons or Number of electrons.
the answer is 142, you have to subtract the number of protons from the mass number and you get the number of neutrons. Neutrons + Protons = Mass Number
Mass number = # protons (or atomic number) + neutronsNeutrons = Mass number - # protons (or atomic number)
The atomic number is the number of protons. The atomic mass is the the mass of the neutrons and protons combined.
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
Atomic number = Number of protonsMass number = Number of protons + Number of neutrons.
