The tendency of electrons is to occupy orbitals of lowest energy first, in accordance with the aufbau principle. This principle states that electrons fill orbitals from lowest to highest energy levels in order to achieve the most stable electron configuration.
Aufbau principle
Hydrogen's electron configuration is 1s1. It has only one electron. It is located in the first energy level.
hydrogen has only one electron so after you remove that electron you do not have any electrons left to remove so hydrogen doesn't have a 2nd ionization energy. hydrogen has 1 proton and 1 electron.
Electrons located in the innermost energy levels (such as the 1s level) have the lowest energy. These energy levels are closest to the nucleus and are filled first in an atom according to the aufbau principle.
The first and second principle energy levels contain only s and p sublevels. The first level has only an s sublevel, while the second level has both s and p sublevels.
No. Hydrogen has only one
The second principle energy level is designated as the n=2 energy level in an atom. Electrons in this energy level have higher energy than those in the first energy level. The second energy level can hold up to 8 electrons.

The tendency of electrons is to occupy orbitals of lowest energy first, in accordance with the aufbau principle. This principle states that electrons fill orbitals from lowest to highest energy levels in order to achieve the most stable electron configuration.
The principle you are describing is known as the principle of energy conservation, or the principle of the conservation of energy. This principle states that energy can neither be created nor destroyed, only transformed from one form to another.
The principle is: electrons fill first the lower energy levels.
No, the tendency is to fill out lower energy levels first.
Aufbau principle
The Principle of the Conservation of Energy states:Energy cannot be created, neither can it be destroyed. It can be changed from one form of energy into another form of energy(example thermal energy may be converted into light energy).
Hydrogen is the only element in the first period to not have a full outer energy level.
