The most common isotope of calcium (40Ca) has 20 neutrons. You can find this out by subtracting the number of protons (atomic number, 20), from the total AMU's of 40. About 96% of calcium on Earth is calcium-40.
Calcium also has eight other isotopes, 41Ca through 48Ca, five of which are radioactive. The second-most prevalent stable isotope is 44Ca which is about 2% of all calcium.
The number of neutrons is the difference between the Atomic Mass of an isotope and the atomic number of the element; each isotope of calcium has a different number of neutrons.

Depending on the isotope, it has 20, 22, 23, 24, 26, or 28 neutrons. The most common isotope has 20 neutrons.

Calcium-41 has 21 neutrons.
Number of neutrons = mass number - atomic number = 40 - 20 = 20 neutrons
it depends on the isotopes of calcium e.g. Calcium-40 has 20 electrons and 20 neutrons Calcium-44 has 20 electrons and 24 neutrons To find out the number of neutrons for Calcium you take the Isotope number (x) minus away the number of electrons (20) e.g. Calcium-x Calcium-x has 20 electrons and (x-20) neutrons.. OR you take the relative atomic mass (x) and subtract it with the number of electrons (20) (x-20) = neutrons
Calcium has 2 valence electrons
The answer to this type of question may always be found by subtracting the atomic number from the atomic mass. For calcium 45 - 20 = 25 neutrons.
Calcium-41 has 21 neutrons.
20 neutrons
The most stable isotope, calcium-40 has 20 neutrons.
calcium has 20 neutrons and electrons
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
The number of neutrons is the difference between the Atomic Mass of an isotope and the atomic number of the element; each isotope of calcium has a different number of neutrons. See the link below for calcium isotopes.
There are 20 neutrons in an atom of Calcium.
Number of neutrons = mass number - atomic number = 40 - 20 = 20 neutrons
it depends on the isotopes of calcium e.g. Calcium-40 has 20 electrons and 20 neutrons Calcium-44 has 20 electrons and 24 neutrons To find out the number of neutrons for Calcium you take the Isotope number (x) minus away the number of electrons (20) e.g. Calcium-x Calcium-x has 20 electrons and (x-20) neutrons.. OR you take the relative atomic mass (x) and subtract it with the number of electrons (20) (x-20) = neutrons
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
