Question

Which of the following Statements are NOT true about the periodic table?

A. The properties of elements are function of atomic weights.
B. The properties of elements are function of atomic numbers.
C. Elements having similar outer electronic configuration are arranged in same period.
D. An element's location reflects the quantum numbers of the last filled orbital.
E. The number of elements in a period is same as the number of atomic orbitals available in energy level that is being filled.

(a) A, C and E Only \quad (b) D and E Only \quad (c) A and E Only \quad (d) B, C and E Only

Evaluating each statement:

- (A) "Properties are function of atomic weights" — ❌ FALSE. Properties are periodic function of atomic number (Moseley's law).

- (B) "Properties are function of atomic numbers" — ✅ TRUE.

- (C) "Similar outer electronic configuration → same period" — ❌ FALSE. Elements with similar outer electronic configuration are in the same group, not period.

- (D) "Element's location reflects quantum numbers of last filled orbital" — ✅ TRUE. Period = principal quantum number; b
