Question
The maximum number of electrons is given by the formula
- n2
- n
- 2n2
- 2n
Hint:
The maximum number of electrons in an orbit can be calculated by 2n2.
The correct answer is: 2n2
- The maximum number of electrons in an orbit can be calculated by using the formula 2n2.
- The 'n' stands for the orbit number.
- Orbit numbers can be considered from 1, 2, 3, 4...
- The maximum number of electrons that can be held by an orbit can be determined by multiplying the square value of the orbit's serial number by 2.
