Chemistry · Electronic configuration of elements and extra stability of half-filled and completely filled orbitals
Which of the following element is represented by electronic configuration
Which of the following element is represented by electronic configuration \( \mathbf{1} \boldsymbol{s}^{2} \mathbf{2} \boldsymbol{s}^{2} \mathbf{2} \boldsymbol{p}_{\boldsymbol{x}}^{1} \mathbf{2} \boldsymbol{p}_{\boldsymbol{y}}^{\mathbf{1}} \boldsymbol{2} \boldsymbol{p}_{z}^{1} \)
- A. Nitrogen
- B. Oxygen
- C. Fluorine
- D. sulphur
Step-by-step solution
The electron configuration 1s² 2s² 2p_x¹ 2p_y¹ 2p_z¹ sums to 7 electrons (2+2+1+1+1=7), which corresponds to atomic number 7. The element with atomic number 7 is nitrogen.
