Write the electronic arrangement for :
Carbon $(\mathrm{atomic}\mathrm{mass}=12,\mathrm{atomic}\mathrm{numbers}=6)$

Carbon:

1. Carbon is a non-metallic element and is denoted as $\mathrm{C}$.
2. The atomic number of Carbon is 6 $(\mathrm{Z}=6)$.
3. Thus, the distribution of electrons is $2,4$.
4. This means that 2 electrons are present in the K shell and 4 electrons in the L shell.

Hence, the electronic arrangement for Carbon is $2,4$.
