Question:
Orbital is:
Orbital is:
Show Hint
An orbital is a region of space around the nucleus where there is a high probability of finding an electron, as described by quantum mechanics.
Updated On: Apr 22, 2026
- circular path around the nucleus in which electrons are revolving
- space around the nucleus where the probability of finding the electron is maximum
- amplitude of electronâs wave
- None of the above
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the definition of an orbital.
An orbital refers to the region in an atom where there is a high probability of finding an electron. It is not a fixed path like a planet orbiting the Sun. Instead, it is a three-dimensional probability distribution of where the electron is likely to be found.
Step 2: Analyze the options.
- (1) Circular path around the nucleus: This is incorrect, as electrons do not move in fixed paths but in orbitals.
- (2) Space around the nucleus where the probability of finding the electron is maximum: This is the correct definition of an orbital.
- (3) Amplitude of electronâs wave: This is related to the wave function, but it is not the definition of an orbital.
- (4) None of the above: This is incorrect, as option (2) is the correct definition.
Step 3: Conclusion.
The correct answer is (2) space around the nucleus where the probability of finding the electron is maximum.
