The atomic number of calcium is 20 as it has 20 protons and 20 electrons, they are located outside the Nucleus in the orbits known as energy levels, and are commonly known as shells of the atom. in the first energy level there are 2 electrons, in the second energy level there are 8 electron, in the third energy level there are 8 electrons, and in the fourth energy level there are 2 electrons.

A cation of calcium has a 2 plus charge how many electrons does it have?
calcium has 20 electrons.when it loses 2 electrons, it has 18 electrons.
How many electrons does calcium lose?
Usually calcium loses 2 electrons, that's why calcium is found in Group 2 of the periodic table.
How many electrons are transferred in the ionic bond between Calcium and Oxygen?
Two electrons are transferred between calcium and oxygen to form calcium oxide.
How many electrons are the third energy level of a calcium atom?
There are 8 electrons in the third energy level of a calcium atom.
How many electrons does calcium have in the second energy level?
Calcium atoms have 8 electrons in the second energy level. However, they are not the valence electrons. The outermost electrons in a calcium atom in the ground state are 2 4s electrons. So calcium atoms in the ground state have 2 valence electrons in the fourth energy level.
