Question

the 2nd energy level in the bohr model can hold no more than ______ electrons.

Explanation:

Step1: Recall electron - capacity formula

The formula for the maximum number of electrons in an energy level $n$ in the Bohr model is $2n^{2}$.

Step2: Identify the value of n

For the second energy level, $n = 2$.

Step3: Calculate the number of electrons

Substitute $n = 2$ into the formula $2n^{2}$, we get $2\times2^{2}=2\times4 = 8$.

Answer:

8
