# Write the Distribution of Electrons in Carbon and Sodium Atom?

## Carbon

The atomic number of carbon is 6. The electronic configuration of carbon is

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

The distribution of electrons in the carbon atom is as follows:

• In the first orbit or K-shell = 2 electrons
• In the second orbit or L-shell = 4 electrons

Or, we can write the distribution of electrons in a carbon atom as 2, 4.

## Sodium

The atomic number of sodium is 11 and the electronic configuration of sodium is,

Na(Z = 11) = 1s2 2s2 2p6 3s1

The distribution of electrons in the sodium atom is as follows:

• In the first orbit or K-shell = 2 electrons
• In the second orbit or L-shell = 8 electrons
• In the third orbit or M-shell = 1 electron

Or, we can write the distribution of electrons in a sodium atom as 2, 8, 1.
