The Aufbau principle states that:Select the correct answer below:1. You must place one electron in each orbital in a subshell before doubling up.2. Orbitals will be filled in order of increasing energy, which is generally in order of increasing principal quantum number.3. No two electrons in an atom can have the same set of quantum numbers.4. None of the above

Respuesta :

Answer:

2

Explanation:

The aufbau principle is one of the fundamental principles that guides the filling of electrons into orbitals. In its simplest forms, it principally means that orbital with lower energy are filled first before orbital with higher energy.

In its more composed form. It’s states that orbitals will be filled in order of increasing energy which is generally in order of increasing principal quantum number.
