1.	In an atom the number of electrons in M-shell is equal to the number of electrons in the K and L-shell. Write the electronic configuration of the element.
Answer» The element is Ti (Titanium). Its electronic configuration is 1s²2s²2p⁶3s²3p⁶4s²3d². Reason : 1. Electrons enter M shell after completion of K and L. 2. So the number of electrons in M shell is 10. 3. But after completion of 3p orbital electron enters 4s before entering to 3d. 4. So outermost orbit or shell is N shell. 5. So the atomic number of element is 22. 6. Its electron configuration is 1s² 2s² 2p⁶3s² 3p⁶4s² 3d².

Answer»

The element is Ti (Titanium). Its electronic configuration is 1s²2s²2p⁶3s²3p⁶4s²3d².

Reason :

1. Electrons enter M shell after completion of K and L.

2. So the number of electrons in M shell is 10.

3. But after completion of 3p orbital electron enters 4s before entering to 3d.

4. So outermost orbit or shell is N shell.

5. So the atomic number of element is 22.

6. Its electron configuration is 1s² 2s² 2p⁶3s² 3p⁶4s² 3d².
