Calcium is a non metal element. There are 20 electrons in a single atom.
What is number of electrons for calcium?
A neutral atom of calcium has 20 electrons
What is the symbol for the atom that has 40 electrons?
Technically, any atom could have 40 electrons, but it would have a very weird charge. However, Zirconium has 40 electrons without being an ion.
