1.	(i) 1s^ 2 2s^ 2 2p 3s^ 2 3p6 3d4 4s^ 2 (ii) 1s^ 2 2s^ 2 2p63s^ 2 3p^ 6 3d^ 5 4s^ 1 Which among these is the correct electronic configuration? Give reason.
Answer» ANSWER: ii) 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d⁵ it is the correct electronic configuration and is of Chromium(Cr). Here the HALF FILLED d-orbital is PROVIDING more stability to the atom than the full filled s-orbital. Thus electrons filled up LIKE so. hope this will help you
