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 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 neutrons are in roentgenium?
Roentgenium-272 has 161 neutrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of roentgenium is 111, but Rg has many isotopes each with a different atomic mass and number of electrons.
How many protons and neutrons in meitnerium?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of meitnerium is 109. Each isotope of an element has a different number of neutrons. Meitnerium has 109 protons.

How many protons and electrons does Yttrium have?
The element Yttrium has 89 protrons and 39 electrons The element Yttrium has 89 protrons and 39 electrons The elemetnt Yttrium has 39 proto The elemetnt Yttrium has 39 proto The elemetnt Yttrium has 39 proto The elemetnt Yttrium has 39 proto
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 neutrons in californium?
Number of neutrons = Atomic mass of an isotope - atomic number Atomic number of Cf is 98.
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 valence electrons are in a yttrium atom?
Three. For more information on Yttrium, go to http://en.wikipedia.org/wiki/Yttrium.
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.
How many electrons are in yytrium?
Yttrium's atomic number is 39, therefore there are 39 electrons in it.
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 are in roentgenium?
Roentgenium-272 has 161 neutrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of roentgenium is 111, but Rg has many isotopes each with a different atomic mass and number of electrons.
