 # What is the distribution of electrons in carbon and sodium atom

In atomic physics and quantum chemistry, the distribution of electrons from an atom or molecule into atomic or molecular orbitals is the electron configuration.

## Distribution of electron in Carbon

The number of the electron in carbon is 6, and the electronic configuration of carbon can be written as,

C(Z = 6) = 1s2 2s2 2p2

• The first two electrons are placed in the 1s orbital. The 1s orbital can accommodate two electrons.
• The next 2 electrons of carbon go in the 2s orbital.
• The next two electrons will go in the 2p orbital. The p orbital can hold up to six electrons.

## Distribution of electron in sodium

The number of the electron in sodium is 11, and the electronic configuration of sodium can be written as,

Na(Z = 11) = 1s2 2s2 2p6 3s

• The first two electrons are placed in the 1s orbital. The 1s orbital can accommodate two electrons.
• The next 2 electrons of carbon go in the 2s orbital.
• The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons.
• We will put six in the 2p orbital and then put the remaining one electron in the 3s. (12) (0)
