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?
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).
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 dose hassium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
How many protons electrons and neutrons are in an atom of Y?
Yttrium atom number 39 = 39 protons.There are two isotopes:stable isotope Y89 , with relative atomic mass 89, thus (89-39) = 50 neutronsunstable isotope Y88 , with relative atomic mass 88, thus (88-39) = 49 neutrons(remember p+n=m)
How many neutrons in silver-107?
There are 62 neutrons in silver-107. Silver has an atomic number of 47, which corresponds to the number of protons in the nucleus. By subtracting the atomic number from the atomic mass, we can find the number of neutrons.

What element has a atomic mass of 39.9?
The atomic number is the count of how many protons an atom has in its nucleus (and therefor also the count of how many electrons the neutral atom possesses). The atomic number us unique for each element and positions the element in the periodic table. The element with atomic number 39 is Yttrium (Y).
Atomic number of 2 and atomic mass of 4 how many neutrons?
To find the number of neutrons simply subtract the atomic number from the atomic mass. In this case there are two neutrons.
How many electrons are in yytrium?
Yttrium's atomic number is 39, therefore there are 39 electrons in it.
How many neutrons dose hassium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
How many protons electrons and neutrons are in an atom of Y?
Yttrium atom number 39 = 39 protons.There are two isotopes:stable isotope Y89 , with relative atomic mass 89, thus (89-39) = 50 neutronsunstable isotope Y88 , with relative atomic mass 88, thus (88-39) = 49 neutrons(remember p+n=m)
How many neutrons are in cadmium-116?
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.
How many neutrons in californium?
Californium typically has 20 neutrons in its nucleus.
How many neutrons are in an atom with the mass number being 186?
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
How many neutrons does a cesium 141 have?
The atomic number of cesium is 55. The number of neutrons is the isotope mass number minus atomic number, or in this instance 86 neutrons.
