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 configurations 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. Choose the correct answer from the options given below:

We need to identify which statements are NOT true about the periodic table.

A. The properties of elements are function of atomic weights. This was Mendeleev's original idea but is incorrect. Properties are a function of atomic numbers (modern periodic law). Statement A is NOT true.

B. The properties of elements are function of atomic numbers. This is the modern periodic law. TRUE statement.

C. Elements having similar outer electronic configurations are arranged in same period. Elements with similar outer electronic configurations are in the same GROUP (not period). Elements in the same period have the same principal quantum number. Statement C is NOT true.

D. An element's location reflects the quantum numbers of the last filled orbital. This is true. The period number corresponds to the principal quantum number, and the block/group corresponds to the azimuthal and magnetic quantum numbers. TRUE statement.

E. The number of elements in a period is same as the number of atomic orbitals available in energy level that is being filled. The number of elements in a period equals the number of available orbitals times 2 (since each orbital holds 2 electrons), not just the number of orbitals. For example, Period 2 has 8 elements (4 orbitals × 2). Statement E is NOT true.

Statements that are NOT true: A, C, and E.

The correct answer is Option A: A, C and E Only.
