Question

Copper (Z=29) has same number of unpaired electrons as *



(a) Scandium (Z = 21)

(b) Manganese (Z = 25)

(c) Chromium (Z = 24)

(d) Titanium (Z = 22

​

Answer 1

Answer:

d is the answer of the question

Answer 2

Explanation:

As we know,

magnetic moment

μ=

n(n+2)

where n = no of unpaired electron

so higher the no of unpaired electron, higher is the magnetic moment.

V : 3 paired electrons x

Cr: 6 unpaired electrons y

Mn: 5 unpaired electrons z

We know that number of unpaired electron increases the magnetic moment also increases.

So, y>z>x
