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).
How many blood hunds are there?

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 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.
What are three rules for writing the electron configurations of elements?
Three rules aufbau principle, the pauli exclusion,and the hunds rule
What is the popular animal in Romania?
Hunds, cats, cows, horses, sheeps, hens Bears. deers, doves, sparrows, swallows, hares
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 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 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.
How could it be possible for electrons not to collapse into the nucleus?
To put it simply no an electron can never come out of the nucleus due to the nucleus only containing protons and neutrons. However protons and neutrons are not fundamental in the sense that they cannot be split. Protons and Neutrons, and indeed all hadrons (of which protons and neutrons belong), consist of quarks. Quarks come in two distinct groups, those with a positive charge of 2/3 the elemental change and those with negative 1/3 the elemental change. With six quarks in total each group has three members. A Proton consists of two up quarks and a down quark giving it a positive charge. The neutron consists of one up quark and two down quarks giving it a neutral charge. When an isotope is unstable due to having a ratio of neutrons to protons that is too high a process know as beta plus decay occurs. When an isotope undergoes beta plus decay, one of the down of the quarks in a neutron emits a W- boson, with results in the down quark changing into an up quark. The change turns the neutron into a proton consequently lowering the neutron to proton ration and sometimes forming a stable isotope. The W- boson meanwhile decays into an electron and an electron anti-neutrino.
How to calculate cfse?
crystal field splitting energy is actually the barrier the degenerate d-orbitals which undergo further splitting due the approach of ligand into low lying "t2g" level and higher "eg" while forming a complex. it explains the stability and structure of the complex. so the energy required for an electron to excite from t2g level to eg level is associated with some energy which is equal to this barrier of energy. this is give in general in terms of absobption bands i.e in terms of wave no. in the problems. the amount of energy or wave no. is equal to the delta not, the octa hedral spliting energy. with the addition of one electron with accordance to Hunds rule, the energy rise by =+2/5∆o in the eg level and =-3/5∆o in eg level.so when we multipy the no. of electrons with these two values based on their position in these two level, and add the values of t2g and eg levels we get the cfse of of octahedral complex. i.e ==> 2/5*(no.of e in t2g)+(-3/5)(no.of e in eg level)=∆o the square planar is another important structure which is regularly seen. the splitting of orbitals is exactly oppsite. hence the ∆o value given need to be taken exactly the oppsite for t2g level and eg level. sq.planar and octahedral energies are related as 4/9∆o=∆t where ∆t is the energy of splitting in the squarplanar complex.
