Period in the Periodic Table
The periodic table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties. The elements are ordered in rows called periods, which are numbered from 1 to 7. Each period represents a different energy level or shell in an atom.
Principal Quantum Number
The principal quantum number (n) represents the energy level or shell in which an electron resides. It determines the average distance of an electron from the nucleus and the energy of the electron. The value of n can be any positive integer from 1 to infinity.
Explanation of the correct answer
The correct answer is option 'C', which states that the period in the periodic table denotes the value of the principal quantum number.
Elaboration
1. Atomic Number (a): The atomic number of an element represents the number of protons in the nucleus of its atom. It determines the element's identity and its position in the periodic table. The atomic number increases from left to right across a period, but it does not directly correspond to the period itself.
2. Atomic Mass (b): The atomic mass of an element represents the average mass of its isotopes, taking into account their relative abundance. It is measured in atomic mass units (amu) and is not directly related to the period in the periodic table.
3. Principal Quantum Number (c): The principal quantum number determines the energy level or shell in which an electron resides. Each period in the periodic table represents a different value of n. For example, the first period (n = 1) consists of elements with electrons in the first energy level, while the second period (n = 2) consists of elements with electrons in the second energy level.
4. Azimuthal Quantum Number (d): The azimuthal quantum number (l) represents the shape of the orbital in which an electron is found. It defines the subshells within each energy level. The value of l can range from 0 to n-1, where n is the principal quantum number. The period in the periodic table does not directly correspond to the azimuthal quantum number.
Therefore, the correct answer is option 'C', as the period in the periodic table denotes the value of the principal quantum number (n), which represents the energy level or shell in which an electron resides.

The chemical elements are arranged in a periodic table according to their atomic number (the number of protons in the nucleus), electron configurations, and characteristic chemical properties. A period in the Modern Periodic Table is indicated by the value of the primary quantum number (n) for the outermost shell or the valence shell.
