Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
There are 20 protons in a calcium atom. You can find the number of atoms in any element by looking at the atomic number which is in the top right corner of the element's box on the periodic table. e.g. Ca 20 40.078
Calcium is the element that has the atomic number 20.
The element Calcium (Ca) has 20 electrons according to its atomic number which is 20.
Calcium has 20 electrons and has an atomic weight of 40.078 amu. It is in group 2, period 4 of the Periodic Table, and is a soft gray alkaline earth metal.
calcium (Ca)
The metallic element whose atoms contain 20 electrons each is calcium, with atomic number 20. (The number of electrons in a neutral atom always matches the number of protons, which is the definition of atomic number.)

Calcium
The element with 20 protons, 20 neutrons, and 18 electrons is calcium. Calcium has an atomic number of 20, which tells us the number of protons in the nucleus. The number of protons and electrons should be equal for a neutral atom, therefore in this case the element is calcium.
Calcium has an atomic number of 20. Thus calcium's number of protons is 20. To balance out these protons' positive charges, calcium also is found with 20 negatively charged electrons.
The chemical element with 20 protons and 20 neutrons is Calcium(Ca). The number of protons is equal to the number of electrons, and the number of electrons is equal to the atomic number.
1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons
Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
