Which of the following atomic orbital designations are incorrect?

not quite. 6p is the only correct one. 7f could theoretically exist but doesn't. the other two are wrong.

Are you referring to the exercise on this page:\nhttp://galileo.phys.virginia.edu/outreach/8thgradesol/PeriodicTable.htm\n\nI had never heard of that before (I teach chemistry); sounds like an amusing exercise! Only I can't see why they'd call Francium an element in group13 (IIIA) and period 4 when it is already a real element in group 1A, period 7! Good luck! I'm assigning Gas Law homework currently and have very little time, or else I'd do the exercise!

Hey man..ask both the questions together.Anyways now i will explain you both. Here t means triplet. It means three similar energy orbitals. Others are\nA=Singlet\nE=Doublet\nT=triplet\n\nAlso 2 here dentoes symmetry about the center. i.e 2 are centrosymmetric while one are no. e.g p orbitals being centro symmetric fall in 2 case and sp3 hybrid orbitals fall in 1 case!!

n = 1,2,.....\n l = 0, 1, 2..... n-1\nm = -l, -(l-1)\n\nThe labels  are called quantum numbers, and made their debut in Sommerfeld's elliptical orbit model. They correspond to certain classical features of the orbit: \n\nn= sr. root of (semi major axis)\nl = orbital angular momentum\nm = orientation of the orbit

hey, when you have 2 electrons in the same orbital, you will always have one spinning up and one spinning down... its about balance, if both electrons were spinning the same direction, they could not stay in they're orbits...

Only sigma orbitals show sp mixing.  Generally, when there is a difference of less than ~15 eV between the s and p orbitals you get sp mixing.

INERT GASES\nNOBLE GASES\nRARE GASES\nALL are names given for atoms(not elements) that are unreactive.\nThese  belong to 8 th group of periodic table and they are\nHe,Ne,AR,Kr,Xe,Rn\nThe above names are given because they are highly stable and unreactive. \nActuallly u should not call them elements because they do not form elements and exixts in atomic state because of high stability.

By "shells," do you mean the energy levels of the electron orbitals?  If that's what you mean, all you do is look on the period table and count how many rows from the top the element is.  So H and He each have one electron shell, C, N, O, F, etc. all have two, Si, B, Na, Cl, etc. all have three, and so on.  Sorry about the scattered examples (I was listing them by memory), but hopefully you get the idea.

No; very few isotopes have been given individual names (there are far too many of them). The only ones I can think of are deuterium (hydrogen-2) and tritium (hydrogen-3).

it's basically a system to put electrons in an atom and although they are arbitrarily placed, the place where they are more likely to be is called atomic orbital. there are several of these. \nthe first, called s orbital, will only acommodate 2 electrons, the second, called p orbital, 8 electrons and so on. read more on the source link

The naming is correct. But the molecule can't exist as described. The Chlor-atom must be attached to the methyl-particle, which is attached to the 3-chloro pentane molecule at the 3rd Carbon-atom.

Boron is not a gas.  They are all period II elements, and they all have three orbitals (1s, 2s, 2p).

It is hydrogen (H). Hydrogen must always exist as a compound, forming a covalent bond with another hydrogen atom (H2).\n\nAtoms such as this are called 'diatomic'. There are others (N, O, F, Cl, Br, and I), however, only H is the stuff of the sun.\n\nUse the extra info to dazzle your teacher.\n\n. . .  and if you didn't know, now you do . . .

d\n\n\na is backwards\nb is backwards\nc is wrong cuz H+ are protons, and nothing is pumped into the matrix

You answered your own question. They're arranged in order of weight. Okay, they're not in perfect order, but nearly every periodic table lists the ordinal (1,2,3,4...etc) atomic weight right on it.

The periodic table as of Oct. 2005 according to IUPAC shows 111. But the elements with atomic numbers 112, 114, and 116 have been reported but not have not been fully authenticated as of September 2003 (Pure Appl. Chem. 75(10), pp. 1601-1611, 2003).

Basically the same as the model of the hydrogen atom, but with more of everything!\nEach of the electrons follows it's own path, which are all perfectly circular orbits and are arranged so as to have the maximum distance between orbits possible. I'm not sure about the energy levels, or if the orbits all have the same radius...
