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.

How many protons neutrons and electrons are in Sc atomic number 44?
Scandium (Sc) has atomic number 21, so it has 21 protons and 21 electrons. Its most common isotope, Scandium-45, has 24 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.
How many neutrons are rutherfordium?
For each isotope of Rf the number of neutrons is different.Number of neutrons = Mass number of an Rf isotope - 104
How many neutrons in californium?
Californium typically has 20 neutrons in its nucleus.
If an element has a mass number of 208 and an atomic number of 83 how many neutrons does the element have?
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
How many protons neutrons and electrons are in Sc atomic number 44?
Scandium (Sc) has atomic number 21, so it has 21 protons and 21 electrons. Its most common isotope, Scandium-45, has 24 neutrons.
How many protons neutrons and electrons in Sc with mass number 44?
21 protons, 21 electrons and 23 neutrons
How many neutrons does the element Sc have?
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.
How many neutrons are in 28Al?
number of neutrons = mass number - number of protons = 28 - 13 = 15 neutrons
How many neutrons would be present in the nucleus of an atom of selenium-76?
All selenium atoms have 34 protons, because that is what defines Selenium. The number that comes after an isotope name is the mass number, which is the sum of the protons and neutrons. Because we know the sum of the protons and neutrons, and the number of protons, we can easily deduce the number of neutrons.p=# of protons n=# of neutrons, and mn=mass numberp+n=mnn=mn-pn=(76)-(34)n=42
How many neutrons are in Cu-63?
Number of neutrons = Mass number - Atomic number = 63 - 29 = 34 neutrons
How many neutrons have an atom with a mass number of 20 and 11 neutrons?
How many neutrons would it have if it had 11 neutrons? 11.
How many neutrons are in the nucleus of chloride-37?
Number of neutrons = Mass number - Atomic number = 37 - 17 = 20 neutrons
How many neutrons does a technetium have?
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
How do you find out how many neutrons a atom has?
Mass number = Atomic number (or number of protons) + Number of neutrons
What is the symbol of barium and number of neutrons?
The symbol for barium is Ba. The number of neutrons in a barium atom can vary depending on the isotope. The most common isotope of barium, Ba-138, has 82 neutrons.
How many neutrons does vandium has?
Number of neutrons depends on the isotope. Number of neutrons = Mass number - Atomic number V-51 isotope has 28 neutrons (51 - 23 = 28)
