A$.$ Briefly explain what is wrong with the electronic configuration below for an atom in the ground state. $1s^{2}2s^{2}2p^{6}2d^1$

B$.$

Write the correct configuration keeping the same number of electrons.

For example for Al you would enter $1s22s22p63s23p1$ for full electron configuration.

C$.$

Give the symbol of the element with the corrected electron configuration.
