Answer 2

Among V3+, Ti3+, Mn3+, and Cr3+ which one is colourless are V3+.

• V3+, Ti3+, Mn3+, and Cr3+ are all 3d series metals.
• In the 3d series, those having 0 and 10 electrons in the d orbital are colourless elements.
• It means elements in 3d must be either 0 or 10 electrons.
• In V3+, after the loss of 3 electrons, d electrons don't have any electrons and the only electrons left are 18.
• Because the electronic configuration of valladium is 1s² 2s² 2p6 3s² 3p6 3d3 but after the loss of 3 electrons electronic configuration is 1s² 2s² 2p6 3s² 3p6.
