Calcium has 20 Protons. You can determine the amount of Protons in an Element by checking the top number of an element. This is called the Atomic number.
Calcium has 20 protons
Calcium has 20 protons and Chlorine has 17, so 20+17= 37 protons.
An atom's atomic number tells us how many protons it has. If we reference a periodic table, we see that calcium's atomic number is 20. Thus, calcium has 20 protons.
carbon has : 36000 protons 124000 electrons 348850 calcium
20.
Calcium (element number 20) has 20 protons and 20 electrons.
Calcium has 20 protons and electrons and a number of neutrons different for each isotope..
Calcium has 20 protons.

Calcium has 20 protons and sulphur has 16 protons and hence calcium has more protons
The number of protons in an element will be the same regardless of the isotope or ion. To have a different number of protons would change what type of element it is. So, it is not necessary to say "how many protons does calcium-41 have?" because it is the same as saying "how many protons does calcium have?" The answer is the same in any case, the same as the atomic number, 20.
