Question

chemistry semester 1 exam on level 25-26
possible points: 1.14
the total number of electrons that are able to be in each sublevel are: ______.

• s=2, p=6, d=10, f=14
• s=3, p=6, d=8, f=10
• s=2, p=5, d=10, f=14
• s=1, p=3, d=5, f=7

Explanation:

To determine the correct number of electrons in each sub - level, we use the following rules:

• The \(s\) sub - level has 1 orbital, and since each orbital can hold a maximum of 2 electrons, the \(s\) sub - level can hold \(2\times1 = 2\) electrons.
• The \(p\) sub - level has 3 orbitals. So the maximum number of electrons it can hold is \(2\times3=6\) electrons.
• The \(d\) sub - level has 5 orbitals. Thus, the maximum number of electrons it can hold is \(2\times5 = 10\) electrons.
• The \(f\) sub - level has 7 orbitals. So the maximum number of electrons it can hold is \(2\times7=14\) electrons.

Among the given options, only the first option (\(s = 2\), \(p=6\), \(d = 10\), \(f=14\)) follows these electron - holding rules for each sub - level.

Answer:

A. \(s = 2\), \(p = 6\), \(d=10\), \(f = 14\)
