How are the Pauli exclusion principle the aufbau principle and hunds rule used to write electron configurations using orbital diagrams and electron configuration notation?
The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers, which means each orbital can hold a maximum of two electrons with opposite spins. The Aufbau principle dictates that electrons fill orbitals starting from the lowest energy level to the highest, creating a systematic order for filling electron configurations. Hund's rule states that electrons will occupy degenerate orbitals singly and with parallel spins before pairing up, ensuring maximum stability. Together, these principles guide the construction of electron configurations and orbital diagrams, ensuring an accurate representation of electron distribution in an atom.
What is spin quantum number?
Good question! Experiments show that the electron "behaves" as if it is a spinning ball of charge. But be careful...the electron IS NOT a spinning ball of charge. Instead the concept is quantum mechanical and has no actual classical analogy. why we r taking the spin of the electorn is +1/2 or -1/2 is there any relation bet rotational symmetry
What is the hunds principle?
Hund's Rule states that within a sublevel, electrons will fill empty orbitals before pairing up. This is to maximize the spin of the electrons and stabilize the atom. It helps to explain the arrangement of electrons in an atom's electron cloud.
What is the maximum number of electrons in 3f?
3f can not exist by the Aufbau principle, quantum mechanics and Hunds rules. In level one there is only 1s In level 2 there is 2s and 2p In level 3 there is 3s, 3p and 3d Only in level 4 and beyond is there an f shell. In level 4 there is 4s, 4p, 4d and 4f. The 4f can hold up to 14 electrons.
How many unpaired electrons are in sulfur?
The answer is two.Third shell of sulfur is occupied by 6 electrons:3s2 3px2 3py 3pzof which the first 4 electrons (in 3s2 3px2) are paired (superscipted 2 means 2electrons per sublevel)and the other 2 electrons are unpaired (3py 3pz, no superscript means 1 electron per sublevel).
According to Hunds' rule when electrons occupy orbitals of equal energy one electron enters each orbit until?
All the orbitals contain one electron, with the same spins.

What are the 3 main rules of the electron configuration?
Atoms can have as many electron shells as they need. The first electron shell can only contain 2 electrons but the rest can contain 8. Electron arrangement patterns down a group : the # of complete electrons shells increases by 1. The # of group is the same as the # of electrons in the outer shell. (ex. Group 2 there will be 2 electrons in the outer shell) Electron arrangement patterns across a period : the # of complete electron shells stays the same. The # of electrons increases by 1 each time. When a new period starts, that's when a new shell is added. Hope this was helpful :)
What is a hunds rule?
Hund's rule of maximum multiplicity describes the order in which electrons fill subshells. It states that they will add into degenerate(equal energy level) orbitals to create the greatest multitude of orbitals having an electron in them. Simply, this means that if you were filling the 2p subshell you would first put an electron in the 2px then 2py then 2pz THEN a second electron in 2px then a second in 2py then one in 2pz NOT 1 in 2px 2nd in 2px etc. The orbitals of a subshell must be occupied singly and with parallel spins before they occupy in pairs. Hund's rule states that greater total spin state usually makes the resulting atom more stable, most commonly manifested in a lower energy state, because it forces the unpaired electrons to reside in different spatial orbitals.

What is the difference between atoms and molecuels?
Atoms: Composed of a neutron and proton nucleus, which is surrounded by an electron cloud. Can only be seen with powerful microscopes. Composed of negatively charged electrons that surround a nucleus of positively charged protons and neutrons, who have no charge. Protons and neutrons of the atom's nucleus are bound by nuclear force. In turn, electrons are bound to the atom by electromagnetic force. Molecules: Composed of two or more atoms. Vary in size. Electrically neutral. Opposites attract, and the interaction between electrons and protons of separate atoms creates the chemical bonds that form molecules. Refer the link below too.
