Which statement about a 3p orbital is correct?
A It can hold a maximum of 6 electrons.
B It has the highest energy of the orbitals with principal quantum number 3.
C It is at a higher energy level than a 3s orbital but has the same shape.
D It is occupied by one electron in an isolated phosphorus atom.
ans is D
I'm not really sure why the ans is not A, can someone pls explain, thankyou

A P Subshell has 3 orbitals and each orbital can hold a maximum of 2 electrons. If it were a 3P subshell then the maximum number of electrons that it could hold would be 6. Therefore statement A is incorrect. Statement D is correct as Phosphorus has 3 electrons in its 3P subshell, Each 3P orbital holds one electron.

View attachment 64779 can someone help with this? answer is B
In order for atoms to be in the same plane the bond angle must be 120 degrees
The central carbon atom in 1 and 2 has 3 B.P so the bond angle is 120 while in 3 the central carbon will also make a bond with hydrogen so it will have 4 B.P hence the bond angle will be 109.5 not 120.

sorry if this is a dumb question but what do u mean by B.P?
