WebAs a reducing agent, a halide ion loses an outermost electron and the ability to lose this electron depends on the shielding effect and the ionic radius. The greater the reducing power of a halide, the more easily it can lose electrons. As you move down the group of halides, the attraction between the nucleus and the outer electrons decreases. WebTransition elements show magnetic moment due to spin and orbital motion of electrons. Which of the following metallic ions have almost same spin only magnetic moment? (a) Co2+ (b) Cr2+ (c) Mn2+ (d) Cr3+ Solution: (a, d) Co 2+ (3d 7) and Cr 3+ (3d 3) have 3 unpaired electrons. Hence they have almost same spin only magnetic moment.
