Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
From the Periodic Table, the atomic number of calcium is 20. This is the number of protons in an atom of calcium. In a neutral atom, the numbers of protons and neutrons are the same, so in a neutral atom of calcium, there are 20 protons and 20 neutrons.
Calcium's atomic number is 20 and Mass number is 40. That means that it has 20 protons, 20 neutrons, 20 Electrons
The atomic number of calcium is 20. So there are 20 protons and 20 electrons in calcium.
A Ca atom has 20 electrons and 20 protons. Find this by looking at the atomic number.
Calcium has 20 protons and 20 electrons
20
The number of electrons should = the number of protons.
Calcium (element number 20) has 20 protons and 20 electrons.
6 electrons, protons, and neutrons.

Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Calcium's atomic number is 20. That means that it has 20 protons. To make it neutral then, an atom of calcium must also have 20 electrons.
Calcium, as an element, has 20 electrons. But when becomes an ion, it loses two electrons, becoming Ca+2. Therefore, as an ion, calcium has only 18 electrons.18
20 protons and 20 electrons
There are 20 p , n , e- in an atom of calcium. Its atomic number is also 20.
20 (any more or less and it would be an ion not an atom)
The number of electrons should = the number of protons.
carbon has : 36000 protons 124000 electrons 348850 calcium
There are 20 electrons in a calcium atom.
Well, first, I feel I should point out that if the atomic number is not 20, then it's not calcium.A neutral atom of calcium has 20 protons and 20 electrons.
Calcium (element number 20) has 20 protons and 20 electrons.
Generally an atom has the same number of protons and electrons. Nitrogen has seven protons.
First, calcium oxide is an ionic compound and so does not form molecules. In one formula unit (ionic equivalent of a molecule) of calcium oxide there is 1 oxygen (8 protons) atom and 1 calcium atom (20 protons) for a total of 28.
