In an atom, electrons are in "shells", the first shell is around the center of the atom and holds a maximum of 2 electrons. Each subsequent shell out, will hold a maximum of 8 electrons. there is no maximum number of shells.
according to MOT each energy level can be occupied by 2 electrons which must have opposite spins these pairs of electrons considered to occupy molecular orbital. so molecular orbital is formed from the overlap of the atomic orbitals of the atoms making up the bond.
Hund's rule: "Two electrons cannot share the same set of quantum numbers within the same system." There is room for only two electrons in each spatial orbital (according to Pauli exclusion principle, mentioned in question).
The electrons fill each of the five orbitals, so there is 1 electron in each of the five orbitals. Then the 6th electron would pair its spin with the first orbital, the 7th would pair its spin with the 2nd orbital, etc.
an atom has different energy orbitals: s, p, d, and f. each orbital can hold two electrons. the outside energy or highest energy levels of electrons is called the valence shell or valence electrons. for an atom to be stable it wants the electron configuration for the valence shell to be "s2, p6." to answer your question the outer level of an atom can hold 8 electrons. it is called the valence shell.
The arrangement of electrons in an atom.
Covalent bonds are formed when atoms share electrons. Let's take hydrogen for example. To be the most "happy" atoms want their outermost orbital full of electrons. Hydrogen has only one electron in its 1s orbital, but the 1s orbital can hold two electrons. Hydrogen wants two electrons to be "happy" so it will do what it takes to get them. If a hydrogen atom bumps into another hydrogen atom they can both become "happy" as each atom will share its electron with the other atom, giving each a full outermost orbital with the help of the other atom's electron. This is what creates the bond in covalent bond as the hydrogen atoms are "happier" together with a full orbital than they would be with a half-full orbital apart.
They can and they do, when outside an atom. Within an atom, it does not happen because each electron is within a very specific orbital that makes collisions impossible.
6 electrons can ocupy the 2p, 3p, 4p, and so on. each p subshell has 3 orbitals, and each orbital can hold up to 2 electrons, so each p subshell can hold up to 6 electrons total.

Electrons orbit around the nucleus in an atom at different levels. The space between each level is referred to as an orbital.
The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.
s-orbital = 2e- (s) orbital can hold 2 electrons, each with opposite spin. p-orbital = 6e- (p) orbital can hold 6 electrons in 3 suborbitals, so 2 electrons in each d-orbital = 10e- (d) orbital can hold 10 electrons in 5 suborbitals, so 2 electrons in each f-orbital = 14e- (f) orbital can hold 14 electrons in 7 suborbitals, so 2 electrons in each
When n=2, you have an s orbital with 2 electrons, and you have 3 p orbitals each with 2 electrons (total of 6). So, total number of electrons for n=2 is 8 electrons.
Atoms are neutral in general. Every atom has a nucleus which consists of protons and neutrons. The nucleus in every atom is surrounded by electrons. The electrons are arranged around the nucleus in several shells or orbits. Each orbit has a probability of occurrence of specific density of electrons in the orbits called as orbital. The first shell or lower most shell consists of s-orbital which has only 2 electrons. The next shell consists of s-orbital which possesses 2 electrons as well as p-orbital which possesses 6 electrons. The second shell has 8 electrons and so on. If the outer most shell does not have eight electrons, then this atom either give away electrons or accept electrons to make up the outer most shell electrons as total 8. If the atom has the tendency to give away electrons then the atom attains positivity. The positivity of the atom is represented as positive ion. If the atom has the tendency to accept electrons then it gains lot of negative charge. This negativity results due to acceptance of negative charge and is represented as negative ion.
There can only be 2 electrons in each single orbital, and they will be on opposite sides of the electron cloud (orbital).
