Chemistry-Transition Elements
NEET Chemistry Transition Elements Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) Lanthanum (i) 4f subshell (b) Actinoids (ii) +3 oxidation state (c) Lanthanoid Contraction (iii) Radioactive elements (d) Transition Elements (iv) d orbitals partially filled
Choose the correct matching:
A
a-ii, b-iii, c-i, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-iv, b-i, c-ii, d-iii
D
a-iii, b-iv, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
Lanthanum primarily exhibits a +3 oxidation state, actinoids are known as radioactive elements, lanthanoid contraction refers to the decrease in size due to the filling of the 4f subshell, and transition elements have partially filled d orbitals, which significantly influences their properties.
