At the ground state, it is easier to fill the first energy level than the second because the second energy level is located farther away and takes more energy to get there.
Electrons fill the 1st energy level first because it has the lowest energy and is closest to the nucleus. Electrons are attracted to the positively charged nucleus and fill the energy levels in order of increasing distance from the nucleus.
The outermost electrons of vanadium are located in the 4s and 3d orbitals. These electrons generally occupy the 4s orbital before filling the 3d orbitals.
The first energy level can hold a maximum of 2 electrons, filling the 1s orbital. The second energy level can hold a maximum of 8 electrons, filling the 2s and 2p orbitals.
the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons
If the first energy level is complete with two electrons, then the elements hydrogen and helium have two elements in their electron configuration. Hydrogen has one electron in its first energy level, while helium has two electrons filling its first energy level.
Nitrogen has 7 electrons. In the highest occupied energy level (n=2), there are 5 electrons, filling the 2s and 2p orbitals.

An atom with 12 electrons will have two electrons in the first energy level and the remaining 10 electrons in the second energy level. This follows the electron configuration pattern of filling the lower energy levels first before moving to higher energy levels.
The highest occupied energy level for magnesium is the third energy level. After filling the 1s and 2s orbitals, magnesium fills the 2p orbital before moving on to the 3s orbital.
The Aufbau principle states that in the ground state of an atom, electrons fill orbitals starting with the lowest energy level first. This principle allows us to predict the electron configuration of an atom by following the order of increasing energy levels.
Carbon's outermost energy level contains 4 electrons, and it needs 4 more electrons to have this energy level filled (total of 8 electrons).
Magnesium has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level, for a total of 12 electrons.
The electrons fill in the lowest energy orbital that is available. Electrons in the 4s orbital have a lower energy level than electrons in the 3p orbital, so the 4s orbitals are filled with electrons first.
In the second energy level of an atom, there can be a maximum of 8 electrons. Magnesium has 12 electrons in total, with 2 electrons in the first energy level and 8 electrons in the second energy level.
Each inner energy level of an atom can hold a maximum number of electrons. Electrons orbit around the nucleus of an atom in shells. Each shell has a set maximum number of electrons it can hold, and the shell has to be completely filled before electrons can start filling up the next shell.
An argon atom has 2 electrons in its first energy level, 8 electrons in its second energy level, and 8 electrons in its third energy level.
