Question

Arrange the following in order of their increasing atomic number \[ A.\ \mathrm{V} \] \[ B.\ \mathrm{Sc} \] \[ C.\ \mathrm{Mn} \] \[ D.\ \mathrm{Ni} \] Choose the correct answer from the options given below:
• \( \mathrm{C < D < A < B} \)
• \( \mathrm{A < B < C < D} \)
• \( \mathrm{B < C < A < D} \)
• \( \mathrm{B < A < C < D} \)

• A. \( \mathrm{C < D < A < B} \)
• B. \( \mathrm{A < B < C < D} \)
• C. \( \mathrm{B < C < A < D} \)
• D. \( \mathrm{B < A < C < D} \)

Hint:

Remember the first transition series order: \[ \mathrm{Sc < Ti < V < Cr < Mn < Fe < Co < Ni < Cu < Zn} \] Atomic number increases from left to right in a period.
