Who stated that an electron occupies an orbital with the lowest energy level first before it will occupy a higher one?
If you are referring to the Aufbau Principle, than I believe it was the Danish physicist Niels Bohr who discovered it around 1920. However, instead of being named after a person, it came from the German phrase Aufbauprinzip which literally translates to "building-up principle."

What states that an electron occupies the lowest energy orbital that can receive it?
The principle that states an electron occupies the lowest energy orbital available is known as the Aufbau principle. According to this principle, electrons fill atomic orbitals in order of increasing energy levels, starting from the lowest energy level. This process continues until all the electrons are placed in the available orbitals, ensuring that the most stable electron configuration is achieved.
What does electron orbital describe?
An electron orbital describes the probable location of an electron within an atom. It represents the three-dimensional region where an electron is most likely to be found, based on the electron's energy level, shape, and orientation within the atom. Each orbital can hold a maximum of two electrons with opposite spins.
Why is not there 3d2 instead of 4s2?
In the electron configuration of an atom, the 4s orbital is generally filled before the 3d orbital due to the lower energy level of the 4s orbital. This follows the Aufbau principle, where electrons fill orbitals in order of increasing energy. Thus, in the electron configuration of an atom, the 4s orbital is filled before the 3d orbital, leading to the configuration 4s2 instead of 3d2.
How do you use aufbau principle to determine electronic configuration?
Each electron occupies the lowest energy orbital. Orbitals related to energy level are of equal energy.
These vary in the number of electron in the highest energy level?
Transition metals vary in the number of electrons in the highest level. Alkaline earth metals have two electrons in the highest energy level.

The energy of an electron varies depending upon which energy level that electron occupies.?
Yes, the energy of an electron does vary depending on which energy level it occupies.

Can you use the word orbital in a sentence?
The Orbital sentence ( An orbital adapter can conspicuisully be preserved in a contenental heat production obseerved from sunlight.)
What is the smallest and least energetic path of the electron around a nucleus?
The smallest and least energetic path of an electron around a nucleus is the ground state, or lowest energy level. In this state, the electron occupies its lowest energy orbital closest to the nucleus.
The energy of a electron varies depending upon which energy level that electron occupies?
true !
Does energy of an electron varies depending upon which energy level that electron occupies?
true
Is the energy of a electron varied depending upon which energy levelthat electron occupies?
Yes.
What is energy of electron when it is closest to the nucleus?
The energy level closest to the nucleus is the 1s orbital and can hold 2 electrons as do all s orbitals. Every electron orbital has a distinct shape and number. The 1s orbital has the same shape the 2s orbital and the 3s orbital and so forth. There are other orbital shapes such as p, d, and f. Regardless of the number or level of the orbital, all p orbitals are the same shape and all d orbitals are the same shape. Orbitals differ in distance from the nucleus and the distance is indicated by the number before the orbital shape.
What does the first quantum number (n) describe?
Which orbital is being occupied ^^^^ WRONG UPDATE 1/12/16: APEX ANSWER IS The energy level of the electron.
Why is not there 3d2 instead of 4s2?
In the electron configuration of an atom, the 4s orbital is generally filled before the 3d orbital due to the lower energy level of the 4s orbital. This follows the Aufbau principle, where electrons fill orbitals in order of increasing energy. Thus, in the electron configuration of an atom, the 4s orbital is filled before the 3d orbital, leading to the configuration 4s2 instead of 3d2.
What is the energy of the electron in a hydrogen atom in an excited state of 5s1 when considering its configuration?
The energy of the electron in a hydrogen atom in an excited state of 5s1 is higher than in the ground state. This is due to the electron being in a higher energy level, specifically the 5s orbital. The configuration of the electron in this excited state indicates that it is in the fifth energy level and occupies the s subshell.
