300 sir
the 2s orbital is at a higher energy level
What is the difference between the place value of the 2s in 8 234 260
It is (1500 + 2000)/2 = 1750
You can tell the difference between 2s sub-shell and 2p sub-shell by checking their energy levels whereby a 2p orbital has a higher energy level compared to a 2s orbital.
You can tell the difference between a 2s sub-shell and 2p sub-shell from their energy levels, because a 2p sub-shell is a higher energy level than a 2s sub-shell.
