Calcium(Ca) is the 20th element in the periodic table and its symbol is ‘Ca’. The electron configuration of calcium and the orbital diagram is the main topic in this article. Also, valency and valence electrons of calcium, and compound formation, bond formation have been discussed. Hopefully, after reading this article you will know in detail about this.

The total number of electrons in calcium is twenty. These electrons are arranged according to specific rules of different orbits. The arrangement of electrons in different orbits and orbitals of an atom in a certain order is called electron configuration. The electron configuration of calcium(Ca) atoms can be done in two ways.

Electron configuration through orbitElectron configuration through orbital

Electron configuration through orbitals follows different principles. For example Aufbau principle, Hund’s principle, Pauli’s exclusion principle. There is an article published on this site detailing the electron configuration, you can read it if you want.

Calcium(Ca) electron configuration through orbit

Scientist Niels Bohr was the first to give an idea of the atom’s orbit. He provided a model of the atom in 1913. The complete idea of the orbit is given there. The electrons of the atom revolve around the nucleus in a certain circular path. These circular paths are called orbit(shell). These orbits are expressed by n.

Quality education can build a beautiful society. I’m Farhan Sadik. I used to enjoy chemistry from school life. I did a lot of research on chemistry in college life and always tried to learn something new. One of the topics of my research is the periodic table. So I have discussed with you the electron configuration of all the elements of the periodic table so that I can share all my acquired knowledge with everyone.
