For the electrons of oxygen atom, which of the following statement is correct?
A
for an electron in a 
-orbital is the same as 
for an electron in a 
-orbital. B
An electron in the 
-orbital has the same energy as an electron in the 
-orbital.
-orbital has the same energy as an electron in the -orbital. C
for an electron in 
-orbital is the same as 
for an electron in a 2s-orbital. D
The two electrons present in the 
-orbital have spin quantum number 
with opposite sign.
-orbital have spin quantum number with opposite sign.
Text Solution
Verified by ExpertsThe correct answer is:
D
Among the given statements, is correct while other are incorrect.
The correct form are
• Electrons in 
and 
-orbitals have different screening effect. Hence, their 
is different. 
of 
-orbital 
of 
-orbital
• Energy of 
-orbital < energy of 
-orbital.
• 
of 1s -orbital 
of 2s -orbital.
