The most stable isotope, calcium-40 has 20 neutrons.
Calcium-41 has 21 neutrons.
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.
20
Calcium has 2 valence electrons
Most naturally occurring calcium atoms have 20 neutrons, but they may also have 21, 22, 23, 24, 26, or 28. Isotopes with 21, 26, or 28 neutrons are radioactive. The isotopes with 21 neutrons are formed from isotopes with 20 neutrons which underwent neutron activation. Whether a calcium atom is positively charged or neutral does not affect how many neutrons it has.
