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 is the region in which a electron is most likely to be found?
in my cereal bowl.
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.
Is there any situation where an electron will have a charge not quantized ExOutside of an atom and if so what would happen if it had exess energy when it goes to an orbit?
The charge of an electron is always −1.602176487(40)×10−19 Coulomb. If an electron is ejected from it's orbital the energy it absorbs is in the form of kinetic energy i.e. how fast it moves. If the electron goes back into an orbital it will only be allowed in an orbital that allows for it's energy. If an atom has an electron and that electron absorbs the energy from an incoming photon it may jump up to a higher orbital or it may be ejected. The ejected electron is the principle of the photo-electric effect.
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 shape of the orbital influences the electrons?
The orbitals represent the possibility to find the electron at a particular place around the nucleus.Its an abstract term.The orbital can't affect the electron because the electron itself forms the orbital.So the orbital does not affect the electron, the electron affects the shape of the orbital.More specially, the orbital has some kind of shape because of the specific energetic condition of the electron.And with these specific, energetic conditions only specific shapes are ''allowed''.
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.
Is the energy of a electron varied depending upon which energy levelthat electron occupies?
Yes.
Does energy of an electron varies depending upon which energy level that electron occupies?
true
The energy of a electron varies depending upon which energy level that electron occupies?
true !
How are electrons placed into an orbital shell?
Electrons enter the orbitals on the basis of increasing energy of sub-shells. Also, when an electron occupies an orbital another electron cannot occupy that orbital until all other orbitals of that sub-shell have atleast 1 electron.
Which electron is on average further from the nucleus an electron in a 3p orbital or an electron in a 4p orbital?
An electron in a 2s orbital is on average closer to the nucleus.
What is penetration effect?
Electron in s-orbital is closer to nucleus than electron in p-orbital and electron in p-orbital is closer to nucleus than electron in d-orbital and so on. So,more energy is requried to remove electron from s-orbital than electron in p-orbital in spite of both having same principal quantum number. Similarly, p orbital will require more energy than d-orbital. this is called penetrating effect. it decreases in order s>p>d>f>... Note that Orbital should have same "n"
What is an electron feature characterized by specific energy?
Orbital
What is the first energy level of an electron?
The K shell's 1s orbital is te first energy level of an electron.
What is the region in which a electron is most likely to be found?
in my cereal bowl.
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.
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.
