Calcium
Calcium
Calcium is an element, which means that it is made up protons/electrons and neutrons. Each calcium atom contains a total of 20 protons/electrons, and 20 neutrons.
Calcium (element number 20) has 20 protons and 20 electrons.
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 atomic number for the element gold is 79. This means there are 79 electrons in an atom of this element.

Phosphorous
This element is xenon.
Calcium (element number 20) has 20 protons and 20 electrons.
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
