In each of sets of terms, circle the one term that does not belong. then explain your reasoning. 1. electron configuration, planck’s constant, aufbau principle 2. spectrum, amplitude, wavelength 3. hertz, quantum, photon 4. hund’s rule, pauli exclusion principle, heisenberg uncertainty principle 5.atomic orbital, frequency, energy level

1. Planck’s constant

2. amplitude

3. hertz

4. Heisenberg uncertainty principle

5. frequency

Explanation:

Out of the option 1 :-

electron configuration, Planck’s constant, aufbau principle

The term which does not belong to the above pattern is:- Planck’s constant

This is because:-

Aufbau principle states that the electrons fill the atomic orbitals in the electron configuration from the lowest energy to the highest energy levels in ground state.

Out of the option 2 :-

spectrum, amplitude, wavelength

The term which does not belong to the above pattern is:- amplitude

This is because:-

Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.  In order of the increasing frequency and the photon energy and the decreasing wavelength the spectrum are:  

radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

Out of the option 3 :-

hertz, quantum, photon

The term which does not belong to the above pattern is:- hertz

This is because:-

The quantum of light is known as photon.

Out of the option 4 :-

Hund’s rule, Pauli exclusion principle, Heisenberg uncertainty principle

The term which does not belong to the above pattern is:- Heisenberg uncertainty principle

This is because:-

The first two are the laws for filling the electronic configuration.

Pauli Exclusion Principle:-

It states that no two electrons present in an atom or a molecule can have same set of the four quantum numbers.  

Even if the two electrons are present in same state which means that if it is present in the same orbital , n, l and m are same but still the forth quantum number which is spin quantum number is different for them. Both the two electrons have opposing spins having value either or .

Hund's rule of maximum multiplicity:-

Firstly, every orbital which is present in the sublevel is singly occupied and then the orbital is doubly occupied.

Out of the option 5 :-

atomic orbital, frequency, energy level

The term which does not belong to the above pattern is:- frequency

This is because:-

According to the Bohr theory, the energy level in which the elctron resolves is known as atomic orbital.
