Question

how many electrons can fit in the second orbital and beyond? 2 1 20 8

Explanation:

Step1: Electron capacity formula

The formula to calculate the number of electrons in a shell is \( 2n^{2} \), where \( n \) is the principal quantum number.

Step2: Calculate for \( n = 2 \)

For the second orbital (\( n = 2 \)), substitute \( n = 2 \) into the formula: \( 2\times2^{2}=2\times4 = 8 \).

Answer:

8
