Chemistry Question on Some basic concepts of chemistry
Which of the following is not a transition element?
A
Sc
B
Pt
C
Ag
D
Zn
Answer
Zn
Explanation
Solution
Among the given options:
(A) Sc (Scandium) is a transition element.
(B) Pt (Platinum) is a transition element.
(C) Ag (Silver) is a transition element.
(D) Zn (Zinc) is not a transition element.
Zinc is classified as a post-transition metal because it does not have partially filled d orbitals in its ground state. Instead, its outermost electron configuration is [Ar] 3d10 4s2, with a completely filled 3d orbital.
Therefore, the correct answer is (D) Zn.
