-
A. Only for s orbitals
-
B. Yes, they are degenerate
-
C. No, they differ greatly
-
D. Only in some molecules
Explanation
When atomic orbitals (like s and p) mix to form hybrid orbitals (e.g., sp³, sp², sp),
The resulting orbitals have the same energy — they are degenerate.
This uniform energy level allows for equal bond strength and geometry, such as in methane (CH₄) with four sp³ orbitals.
Explanation
When the 6d orbital is completely filled, the next electron enters the 7p orbital.
This is based on the Aufbau principle, which dictates that electrons first occupy the lowest energy levels available.
After the 6d orbitals (which can hold up to 10 electrons) are filled,
The 7p orbitals (which can hold up to 6 electrons) become the next lowest energy
کون سا مدار زیادہ توانائی رکھتا ہے؟
-
A. 4d
-
B. 6p
-
C. None of these
-
D. 6d
Explanation
- Among the given orbitals, the 6p orbital has higher energy compared to 4d and 6d.
- Because p orbitals are less stable than d orbitals at the same principal quantum number.
- The order of energy levels depends on the (n+l) rule, where orbitals with higher values have more energy.
