How many neutrons does yttrium have?

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.


How many protons and neutrons in yttrium?

78


What is the number of neutrons in yttrium?

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.


How many protons neutrons and electrons in Yttrium?

Protons: 39 Neutrons: 50 Electrons: 39


What has 20 neutrons and 19 protons?

Yttrium (Y)


How many protons neutrons electrons are in yttrium?

What is the number of protons for yttrium?

The element yttrium (Y) has 39 protons.


What element has 39 protons and 50 neutrons?

The number of protons is equal ti the number of electrons. Yttrium is the element. It is in the d block.


How many protons nuetrons and electrons does yttrium have?

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.


How many neutrons are in an atom of this isotope if the atomic number of yttrium is 39 and the atomic mass of the isotope is 89?

50 because 89(the atomic number, which is the amount of protons+the amount of neutrons)-39(the amount of protons) is 50


How many protons neutrons and electrons are in yttrium have?

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.


How can you use atomic number and mass number to determine the number of protons and neutrons in an atom?

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.


What is the relationship between the number of neutrons and protons in the atom?

Atomic mass = number of protons + number of neutrons Mass number = number of protons + number of neutrons


Is there a relationship between the number of neutrons and protons in the atom is so what type?

Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons


How many protons neutrons and electrons does an element have?

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).


The sum of the protons and neutrons indicates the?

Mass number = number of protons + number of neutrons


What is indicated by the sum of protons and the neutrons?

Mass number = Number of protons + Number of neutrons


What they do mass number?

Mass number is about the neutrons and protons. The total of neutrons and protons.


What is the sum of the protons electrons and neutrons?

Mass number = Number of protons + number of neutrons. Atomic number = Number of protons or Number of electrons.


How much neutrons does Thorium have?

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


What do you subtract to get the numbers of neutrons?

Mass number = # protons (or atomic number) + neutronsNeutrons = Mass number - # protons (or atomic number)


Is the mass number the number of protons and neutrons?

The atomic number is the number of protons. The atomic mass is the the mass of the neutrons and protons combined.


What are the number of protons neutrons and electrons in an element?

Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons


How do you calculate number of protons and neutrons?

Atomic number = Number of protonsMass number = Number of protons + Number of neutrons.
