Calcium is a metal element. There are 20 electrons in a single atom.
Calcium has 20 electrons
calcium has 20 neutrons and electrons
Calcium is a non metal element. There are 20 electrons in a single atom.
20 electrons
Depends on what you mean by number of electrons. Calcium has 20 electrons and oxygen has 8 electrons for a total of 28 electrons. But if you mean how many VALENCE electrons, then the calcium has 2 and the O has 6 for a total of 8 valence electrons.
