Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
For Ca isotope 40 it is 20 neutrons and 20 protons, but there are 5 other naturally occurring (>2%) Ca-isotopes with mass numbers ranging from 42 - 48. Remember: p + n = mass number, so n = m - p
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
