Question

how many electrons can the s sublevel hold?

Explanation:

Step1: Recall electron capacity formula

The formula for the number of electrons a sub - level can hold is \(2(2l + 1)\), where \(l\) is the azimuthal quantum number. For the \(s\) sub - level, \(l = 0\).

Step2: Substitute \(l = 0\) into the formula

Substitute \(l = 0\) into \(2(2l+1)\). We get \(2(2\times0 + 1)\).
First, calculate the value inside the parentheses: \(2\times0+1=1\).
Then, multiply by 2: \(2\times1 = 2\).

Answer:

2
