Question

the electronic configuartion of Cr is Ar4s23d4

true of false

Answer 1

Answer #1

False.

Electronic configuration of Cr is [Ar] 3d⁵ 4s¹ instead of [Ar] 3d⁴ 4s². This is because 3d⁵ is half-filled and thus gain extra stability.

What is the approximate value of the wavelength for the two other peaks? Which one of these three peaks falls in the visible region of the electromagnetic spectrum? The wavelength at this peak is (Amax), and this transition accounts for the color of the complex ion in solution. The energy of the transition occurring at...

If [Cr(H2O).]3+ is violet and [Cr(NH3)6]3+ is yellow, which one of these statements is false ? 750 400 Red Violet 630 430 Orange Blue 590 480 Yellow Green 560 O [Cr(H20)6]3+ has three unpaired electrons. O NH3 is a stronger field ligand than H20. O [Cr(H20)6]3+ absorbs yellow light while [Cr(NH3)6]3+ absorbs violet light. The crystal field splitting energy (A) is greater for [Cr(H20).]3+ than for [Cr(NH3)613+. O [Cr(NH3)613+ is paramagnetic.
