Question
Write the distribution of electrons in carbon and sodium atoms?
Advertisements
Solution
The atomic number of carbon is = 6.
As a result, the first shell (K-shell) contains two electrons, while the remaining four are found in the second shell (L-shell). So, the distribution will be
| K | L |
| 2 | 4 |
The atomic number of sodium is = 11.
Thus, the first shell (K-shell) will have two electrons, the second shell (L-shell) will have eight electrons, and the third shell (M-shell) will have one electron. So, the distribution will be
| K | L | M |
| 2 | 8 | 1 |
