Question

URGENT I ONY HAVE 1HR

the formula for the maximum number of electrons that can occupy a
principal energy level. Use n for the principal quantum number.
a. 2n2                                      b. n2                                       
c. 2n
d. n​

Answer 1

2n²

Step-by-step explanation:

Principal quantum number shows the energy of an electron. It is represented by letter n.

The formula that is used to find the maximum number of electrons that can occupy a principal energy level is given by :

M = 2n²

Where n is principal quantum number associated with that energy level.

Hence, the correct option is (a).
