Orbitals Definition and 236 Threads

Hi. I'm taking o-chem this trimester and we're reviewing some stuff from the end of gen chem last tri that I probably should have had down, but it's not making sense. It's the representations of orbitals around atoms and molecules. I get the s orbital. At least I think so. It forms...

This is a confusing topic. What does it mean to be degenerate? How does this apply to atomic orbitals versus molecular orbitals? Can you point me to a good reference book on the subject?

I'm trying to interpret a research paper on single photon ionization using extreme UV attosecond laser pulses, and I realized I have some very basic questions concerning electrons in an atom. Technically, the answers to these questions are found online and in the literature, but the wording...

Hello I didn't get something about the AO. i.e the electron configuration of C is 1s² 2s² 2p² . So we know that at the 2nd shell this has 4 electrons, 2 in s orbital + 2 in the p, right? How do we find out how the 2 electrons of p are spread in the px, py, pz? Thank you, Panos

for n=2 & l=1 we have P orbital for which magnetic quantum no. can take values -1,0,1 , now in p orbital we have 2Px, 2Py &2Pz each corresponding to vale of m like 2Px for m=-1 and so on , is this correct or 2Px can be represented by 0 0r 1 also .

I have one question about wave functions and molecular orbitals (MO). In the computational quantum chemistry scientists often use Linear Combination Atomic Orbitals (LCAO) to construct MO. \varphi_{i\lambda\alpha}(\vec{r})= \sum\limits_{p=1}^{N}\chi_{p\lambda\alpha}(\vec{r}) C_{i\lambda p}...

I have several questions that I would appreciate if you guys could help me with, I want to understand these conepts as well as possible. In my chemistry textbook it states that the atoms of each element have a spectral signature, and each atom emits a certain wavelength of radiation, for...

I'm not sure why, but I could never really picture & grasp this concept. Say you're drawing the orbitals of an atom, the 1s & 2s orbitals are pretty easy to draw. They are just spheres with a node in between them. Now do these orbitals overlap, or does one start where the node ends? What...

Rsepected sir Please read my doubts in the attachment and kindly answer it. Thankyou.

Hi, I have a question regarding the contribution of some molecular orbitals (e.g HOMO, LUMO) to the total density of states of a two-probe system. How exactly are the contributions of the MO ( that look similar to the DOS plots ) calculated, do they have something to do with the local...

Is there a particular reason why the probability density distribution function of atomic orbitals bears a similarity to the modes on a circular membrane? Is this just a coincidence? Is it not actually that similar?

I asked myself how the orbitals in a solid look like. Assume a crystal with a periodic structure, e.g. NaCl. The electrons in the crystal have energys according to the energy-band-model. Every band consists of that much discrete energy-levels that you might nearly call it continous. I know that...

1: Why are the elements of a basis set taken to be orthogonal? But in real sense atomic orbitals do overlap.

Homework Statement Everybody knows Hydrogen has one electron which resides in K orbit.While explaining Hydrogen bonding we talk about higher orbits while explaining Lyman Balmer,Pashen,Buffet & Brackett series of Hydrogen spectrum.If only one electron resides in first orbit,then how it'll...

Hello. Is there a way of telling from which electron orbital of unstable radioactive isotope an electron will be emmitted (if we take for example that decay mode includes electron emmission)? Because different atoms have different electron orbital configurations (1s, 2p, ..) and there can...

Hey everyone! I was wondering, when orbitals are hybridized, new hybrid Atomic Orbitals (AO) are formed. Now, when these hybrid atomic orbotals bond with another atomic orbitals, are molecular orbitals formed? For example, when 2 Hydrogens bond to form H2, the 1s orbitals overlap to form 2...

I'm having trouble understanding anything dealing with the subject of orbitals, shells, subshells, electron configuration, etc. I'm sure no one on this site is going to want to explain it to me in full or anything like that; I'm not expecting it. Can anyone suggest a website that explains this...

The question isn't exactly like this but this is the jist of it: Give the values of the quantum numbers associated witht he following orbitals: 2p, 3s, and 5d. I ,frankly, do not understand what they are asking for. So can anyone explain this for me. Thanks.

From high school chemistry I learned that orbital is the region where probability of finding an electron is high. (Probability, since electron has no well defined location.) Different types of orbitals have different shape of region. I also learned that different orbitals of the same shell may...

I have searched some books I have on Quantum Physics, and so on, but I still haven't found any useable material to learn about the Pauli exclusion pinciple, atomic orbitals, why the Periodic Table exists, or things like that, in an informal way. Thanks, Neohaven

I never really learned this, and it popped up yesterday. Can someone explain to me how to compound colors are all determined by the d orbitals and would it be only the d orbitals. it would be very helpful, thanks.

For the following molecules and ions, indicate the obitals involved in bond formation. 1) SO2 The central atom is S, and it has 1 double bond with a O and a single bond with the remaining O. There is also 1 lone electron pair. Therefore, a S-O bond is sp^2-p while a S=O bond is sp^2-sp^3...

Please, can someone answer my question? I know the shape of sp hybrid orbital, but want to know about the others ( sp2,sp3,dsp2,dsp3,d2sp3,d3sp3 ). And are there any other type of molecular orbitals?

How would you designate the hybrid orbtial formed by "mixing" one d, one s, and 2 p orbitals? How many of the hybrid orbitals would be formed by the mixing?

I was thinking back to my QM class last semester. My teacher derived what the orbitals of the hydrogen atom should look like. I just realized something a little strange about the result that it did not occur to me at the time to ask: How is it that orbitals resulted from a spherically...

-how does one determine the type of hybridization used in covalent bonding (sp- sp^2...etc)...that is my question...HOW?

Ok, what I need is the following: - program that can draw orbital - it must be free (not to buy) (no copy right, ...) I didn't find one that is free and has a nice graphic.

I have no idea where to start on this: A satellite is in a circular orbit very close to the surface of a spherical planet. The period of the orbit is 1.69 hours. What is density of the planet? Assume that the planet has a uniform density. Perhaps someone could point me in the right...

hey everyone! good morning! can anyone please clarify this statement for me? True of False (correct statement if false) There are five d orbitals at both the fourth and sixth principal energy levels. i said it was false because there's only one d orbital per principal energy level...

Is anybody familiar with LCAO approximation? I'm working on my last problem for this assignment and the class text doesn't really cover it enough for me nor do my reference texts cover it enough. Does anybody know any good references so I can read more on LCAO approximation? Thanks.

which force separates the electrons and nucleus and causes the electrons to orbit? a friend told me that the size of the electron means that the nuclei cannot absorb it, but i am still confused and not sure if he knew what i meant in my question.

d orbitals.. 5 or 6? hey i always thought ther wer 5 d orbitals corresponding 2 quantum number m = -2, -1,..., 2 now i read somwhere that ther wud actually be 6 possible sollutions to schrodigner's equation.. i.e. six d orbitals, and th d z-square orbital is a linear combination of two of...

Just how was it determined from electron wavefunctions calculated by schrodingers equation? For example, if i take the 1S and 2P wavefunctions ( ground state wavefunction against distance from nucleus) http://www.shef.ac.uk/chemistry/orbitron/AOs/1s/wave-fn.html...

Why are orbitals called s, p, d, and f? I know how they work I was just wondering how did they get that specific abbreviation?

How would three P orbitals, X,Y,Z, in the same subshell, give the electrons different quantum energies?

Hello, The geometric form of the water molecule is explained in chemistry books by the hybridization of certain orbitals, in this case the 2p and 2s orbitals.The resulting hybridized orbital then gets the geometric form observed. I know that hybridization is permitted by the fact that...
