Vedclass · Answer

(A) The atomic number of Titanium $(Ti)$ is $Z = 22$. According to the Aufbau principle,electrons are filled in orbitals in increasing order of energy: $1s, 2s, 2p, 3s, 3p, 4s, 3d$. Filling $22$ electrons: $1s^2, 2s^2, 2p^6, 3s^2, 3p^6$ accounts for $18$ electrons. The remaining $4$ electrons are filled as $4s^2$ and $3d^2$. Thus,the configuration is $1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^2$.

The correct electronic configuration of $Ti$ $(Z = 22)$ atom is:
