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:

<p>Let's analyze each statement one by one:</p> <p>$\textbf{A. The properties of elements are function of atomic weights.}$ </p> <p><p>Originally, elements were arranged by atomic weights, but it was later understood that their properties depend on the atomic number (the number of protons) rather than the atomic weight. </p></p> <p><p>Thus, this statement is NOT true.</p></p> <p>$\textbf{B. The properties of elements are function of atomic numbers.}$ </p> <p><p>The periodic table is arranged by increasing atomic number, and an element’s properties directly relate to its number of protons and the corresponding electron configuration. </p></p> <p><p>This statement is true.</p></p> <p>$$\textbf{C. Elements having similar outer electronic configurations are arranged in same period.}$$ </p> <p><p>Elements that have similar outer electronic configurations are actually grouped in the same column (group) rather than the same row (period). </p></p> <p><p>Therefore, this statement is NOT true.</p></p> <p>$$\textbf{D. An element's location reflects the quantum numbers of the last filled orbital.}$$ </p> <p><p>The arrangement of elements corresponds to the electron configurations determined by quantum numbers, especially for the last electron added. </p></p> <p><p>This statement is true.</p></p> <p>$$\textbf{E. The number of elements in a period is same as the number of atomic orbitals available in energy level that is being filled.}$$ </p> <p><p>In an energy level, the number of atomic orbitals does not directly equal the number of elements in a period. For example, period 2 has 1s filled, and then the 2s and 2p orbitals are filled (a total of 4 orbitals), yet there are 8 elements because each orbital can accommodate 2 electrons. </p></p> <p><p>Hence, this statement is NOT true.</p></p> <p>So, the statements that are NOT true about the periodic table are A, C, and E.</p> <p>Thus, the correct answer is: </p> <p>Option A: A, C and E Only.</p>
