Calcium-40/Protons
How many electrons are in a calcium-40 atom?
20 electrons
there are 20 electrons.
How many neutrons does the 40 calcium isotope have?
20 neutrons
In calcium-40, there are 20 neutrons.
How many protons does calcium have?
Calcium/Atomic number
If we could weigh individual atoms of calcium we would find some variation in their mass; this must be due to variations in the number of neutrons in their nucleus as all must have the same number of protons – 20. Atoms which have the same atomic number but different mass numbers are isotopes.

How many protons are in a ca 41 isotope?
What is the number of neutrons in calcium?
There are many isotopes of calcium, ranging from calcium-40 with 20 neutrons, to calcium-48 with 28 neutrons.
How many protons neutrons and electrons does CA have?
Calcium. This element has 20 protons, 20 electrons , and 20 neutrons giving it an atomic mass of 40.
How many neutrons calcium?
However, the number of neutrons in the nuclei of the calcium atoms can vary. Atoms of the same element with different numbers of neutrons are isotopes. There are many isotopes of calcium, ranging from calcium-40 with 20 neutrons, to calcium-48 with 28 neutrons.
What is the atomic mass of calcium?
Atomic Mass of Calcium. Atomic mass of Calcium is 40.078 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.
