It states that every orbital in a given subshell is singly occupied by electrons before a second electron is filled in an orbital. In order to maximize the total spin, the electrons in the orbitals that only contain one electron all have the same spin (or the same values of the spin quantum number).
18 Μαΐ 2021 · Hund's rule specifies the order of electron filling within a set of orbitals. Orbital filling diagrams are a way of indicating electron locales in orbitals.
Shells and subshells are filled in energy level order, so electrons will fill the 4 s subshell before the 3 d shell. Orbitals are filled singly by electrons and will only double up once all orbitals have at least one electron to prevent repulsion by pairing.
The shells are orbital paths that are followed by electrons around the nucleus. Like everything in chemistry, electrons like to follow the path of least resistance. This means that electrons will usually fill up the shells of an atom from the inside out.
26 Μαρ 2020 · When drawing orbital diagrams, we include empty boxes to depict any empty orbitals in the same subshell that we are filling. Carbon (atomic number 6) has six electrons. Four of them fill the 1 s and 2 s orbitals.

20 Ιουλ 2022 · Electrons are added to sublevels according to Hund’s rules which state that every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
