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.
Number of neutrons = mass number - atomic number = 40 - 20 = 20 neutrons
There are 20 neutrons in calcium-41, which is determined by subtracting the atomic number (20, representing number of protons) from the mass number (41, representing total number of protons and 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
A calcium atom typically has 20 protons, 20 electrons, and approximately 20 neutrons.
A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.
20 neutrons
The most stable isotope, calcium-40 has 20 neutrons.
45 neutrons
calcium has 20 neutrons and electrons
Neutrons: 58 Electrons: 45 Protons: 45
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Number of neutrons = mass number - atomic number = 40 - 20 = 20 neutrons
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 calcium-41, which is determined by subtracting the atomic number (20, representing number of protons) from the mass number (41, representing total number of protons and neutrons).
There are 20 neutrons in an atom of Calcium.
