Question

write the set of quantum numbers for the lastly entered electron of oxygen atom.​

Answer 1

Answer:

$\huge{Heya\: Mate}$

$\color{red}{set\: of\:quantum \:numbers,\:for\:the\:lastly\:entered \:electron\:of \:oxygen\:atom}$

↪Oxygen is the eighth element with a total of 8 electrons.

↪the electron configuration for oxygen the first two electrons will go in the 1s orbital.

↪Since 1s can only hold twoelectrons the next 2 electrons for O go in the 2s orbital.

↪The remaining four electrons will go in the 2p orbital

↪There will be ten total since 1s, 2s, 2px, 2py, and 2pz will be used. That is five atomicorbitals for one oxygen atom, and there are two atoms. MO theory uses “conservation oforbitals”, and two oxygen atoms have a total of eight valence atomic orbitals. Therefore, there will be eight molecular orbitals in O2

$\bf{Orbitals\:in\:oxygen}$

Answer 2

MO theory uses “conservation oforbitals”, and two oxygen atoms have a total of eight valence atomic orbitals. Therefore, there will be eight molecular orbitals in O2
