∙ 12y ago
Energy sublevels are labeled using the following letters: s, p, d, f, g...
Each sublevel has an odd number of orbitals.( You can also find out how many electrons an atom has by multiplying the orbital number by 2)
Sublevel Orbitals # of e-
S 1 (x2) 2
P 3 (x2) 6
D 5 (x2) 10
F 7 (x2) 14

Why is it that all of the sub shells in a given shell have the same energy in the hydrogen atom whereas in a many-electron atom the sub shells in a given shell do not have the same energy?
The hydrogen atom only has one energy level (shell). The first energy level also contains only one sublevel, 1s sublevel (subshell), which can only hold two electrons. When you get to the second energy level in the second period on the periodic table, it has two sublevels, the 2s and the 2p sublevels. Both of the electrons in the 2s sublevel have the same energy. The 2p sublevel can hold 6 electrons. All of the electrons in the 2p sublevel have the same energy, which is higher than the energy in the 2s sublevel. So, as we move down the periods on the periodic table, we move from the first energy level to the seventh energy level. Each energy level contains specific numbers of sublevels, and all of the atoms within a particular sublevel have equal energy.

What is Bohr notation?
Bohr notation describes the grouping of electrons within the different periods by orbital shells of an atom. For example, Lead (Pb) is an element in the 6th period, 14th group and has an electron configuration of [Xe] 6s24f145d106p2. Based on electron groupings of those orbitals, lead would have an electron grouping by period of 2 electrons in 1s, 8 in 2s2p, 18 in 3s3p3d, 32 in 4s4p4d4f, 32 in 5s5p5d5f, and 4 in 6s6p for a notation of:2-8-18-32-32-4This notation is not based on electron orbital energy level, but instead by the number of electrons in each period. This is significantly different than the filling of electrons by energy level that would actually group and fill the electrons in ascending energy levels:1s, 2s, 2p3s, 3p4s, *3d4p5s, *4d5p6s, *4f5d6p7s, *5f6d7pNotice specifically that energy levels for the "d" and "f" orbitals are out of sequence within the orbital levels because of their higher energy states relative to their period level. If grouped this way, the notation would look more like:2-2-8-8-18-18-26This notation is very redundant within the first six energy levels and can be confusing when compared with the period levels because of the out-of-sequence orbitals for the 3d, 4d, 5d, 4f, and 5f periods.Also it is counter-intuitive to the periodicity to the sub-atomic organization within the periods while Bohr notation follows it exactly:- 2 elements in period 1, 2 electrons in 1st set notation- 8 elements in period 2, 8 electrons in 2nd set notation- 18 in period 3, 18 in 3rd notation- 32 in period 4, 32 in 4th notation- 32 in period 5, 32 in 5th notation- 46 in period 6, 46 in 6th notation- 46 in period 7, 46 in 7th notation(if you consider all "undiscovered" synthetics in the last two notations)

What is sub-level notation?
sublevel notation shows the electrons and their spins within each orbital. For example the 1s2 electrons would have one arrow pointing up and one arrow pointing down.

Even though zinc is after copper in the periodic table leading to an increase in the nulear charge by 1 which should therefore decrease the radius why is it larger than copper?
Zinc has a filled 3d sublevel and 4s sublevel. There is more shielding from the effective nuclear charge within the filled 3d sublevel and also from the filled 4s sublevel. Copper does not have a filled 4s sublevel; recall that one of the 4s electrons "jumps up" to the 3d sublevel thereby stabilizing it by making it filled with 10 electrons. Because of this, the 4s is only half filled and there is not as much shielding within the 4s sublevel allowing the effective nuclear charge to pull the 4th energy level in more toward the nucleus. This will make the overall size of the atom smaller.
