###### Answer: E

The quantum numbers corresponding to these operators are (always 1 / 2 for an electron ) and respectively. The energy levels in the hydrogen atom depend only on the principal quantum number n . For a given n all the states corresponding to l = 0 … n − 1 {\displaystyle l = 0 \ldots n – 1 } have the same energy and are degenerate.

S = ½ + ½ + ½ − ½ − ½ = ½; and L = 1 + 0 − 1 + 1 + 0 = 1 which is “P” in spectroscopic notation.; As fluorine 2p subshell is more than half filled J = L + S = 3 ⁄ 2 .Its ground state term symbol is then 2S+ 1 L J = 2 P 3 ⁄ 2 .; Atomic term symbols of the chemical elements. In the periodic table because atoms of elements in a column usually have the same outer electron structure …

Electron configuration says at subshell p ( l = 1 ) there are 3 energy level ml =- 1 0 1 but we see only two p1/ 2 and p3/ 2 . for subshell s( l = 0 ) there is only 1 energy level ( ml = 0 ) but here we have 2 . l corresponding to fine structure ml corresponding to hyperfine structure. References

The logarithm of 3 kg is undefined but the logarithm of 3 is 0 .477. I am a 12th grade science student and this struck me as a bit odd. Is there something wrong with the equation pH=-log 10 [H +]. Because [H +] is definitely in N . L – 3 (where N is amount of substance – moles in other words) i.e. mol.dm- 3 .

N 2 O 5 Cl 2 O 7 Mn 2 O 7 OsO 4 [PuO 2 ] 3 + [AmO 6] 5-. The thermal stability of many oxides are higher than fluorides and/or nitrides. eg. ThO 2 ….
