How many electrons in an atom could have these sets of quantum numbers? n=2?
slavikrds [6]
A maximum of 8 electrons can share the quantum number  n = 2.

Principal Quantum number has a symbol of "n". It tells you the energy level on which an electron resides. Y<span>ou need to determine exactly how many </span>orbitals<span> you have in this energy level before you can determine the number of electrons that can share the value of n.
</span>

The number of orbitals you get per energy level can be found using this formula:

<span>no. of orbitals=<span>n</span></span><span>²</span>

Each orbital can hold a maximum of two electrons, the formula would be:

<span>no. of electrons=2<span>n</span></span><span>²</span>

Using the given formulas:

<span>no. of orbitals = <span>n</span></span><span>² </span><span>= </span><span>2</span><span>² </span><span>= </span><span>4</span>

<span>no. of electrons </span><span>=</span><span>2 *</span><span> </span><span>4 </span><span>= </span><span>8 </span>
