Electronic Circuit for Chemical Element with Atomic Number 20

To create an electronic circuit for a chemical element with atomic number 20, we need to consider the electron configuration of the element. The element with atomic number 20 is calcium (Ca). The electron configuration of calcium is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2.

The electronic circuit for calcium can be represented as follows:

Ca: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2

In this circuit, each energy level is represented by a shell, and the electrons are represented by arrows. The number of electrons in each shell is determined by the electron configuration.
