Respuesta :
The energy required to remove second electron from lithium is more as compared to removing fourth electron from carbon
EXPLANATION:
The amount of energy required to remove an electron from an isolated atom is called as ionization energy of the electron.
The second ionization energy of lithium atom is more as compared to fourth ionization energy of carbon atom. It is so because the second electron which is to be emitted from the K-shell of lithium atom, is tightly bound by the nucleus as the orbit is very closer to the nucleus.
In case of carbon, the fourth electron is present in the valence shell.The radius of valence shell is not so close as compared to lithium.The screening effect is also more for carbon as compared to lithium.
Hence, the energy required to remove a second electron from lithium is more that the energy required to remove fourth electron from carbon.
It is easier to take out 4th electron from carbon than 2nd electron from lithium because 2nd electron of lithium is closer to the nucleus.
The electronic configuration for,
[tex]\rm \bold{ Li_3 - 1s^2 2s^2}\\\\\rm \bold{ C_6- 1s^2 2s^2 2p^2}[/tex]
- We can see here the 2nd electron of Lithium is present in first cell. The electron is more strongly bounded with nucleus.
- Whereas in Carbon 4th electron present in valence shell. Hence, the electron will be loosely bounded with nucleus.
Therefore, we can conclude that the it is easier to take out 4th electron from carbon than 2nd electron from lithium.
