Mass Number - Atomic Number = Number Of Neutrons
So for Sc:
45 -21 = 24 neutrons
However there is also an unstable Sc isotope (0.6 s half-life time) with mass number 41, so this one has 20 neutrons.
Sc is actually atomic number 21, there are 21 protons, 21 electrons, and usually 24 neutrons
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.
For each isotope of Rf the number of neutrons is different.Number of neutrons = Mass number of an Rf isotope - 104
Number of neutrons = Atomic mass of an isotope - atomic number Atomic number of Cf is 98.
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
21 protons, 21 electrons and 23 neutrons
Sc is actually atomic number 21, there are 21 protons, 21 electrons, and usually 24 neutrons
The element Scandium (Sc) has 21 protons in its nucleus, which can be determined using its atomic number. To find the number of neutrons, we can subtract the atomic number from the atomic mass: Scandium has an atomic mass of approximately 45. This gives us 45 - 21 = 24 neutrons in a Scandium atom.
Number of neutrons = Mass number - Atomic number = 63 - 29 = 34 neutrons
How many neutrons would it have if it had 11 neutrons? 11.
Mass number = Atomic number (or number of protons) + Number of neutrons
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
Number of neutrons = Mass number - Atomic number = 37 - 17 = 20 neutrons
Number of neutrons depends on the isotope. Number of neutrons = Mass number - Atomic number V-51 isotope has 28 neutrons (51 - 23 = 28)
number of neutrons = mass number - number of protons = 28 - 13 = 15 neutrons
Number of neutrons = Mass number of an isotope - 96
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Pm isotope - 61
