Question

Hund's rule states which of the following?

A) chemical bonds are formed only between electrons with similar spin

B) the attraction between electrons holds atoms together

C) a ground state atom always has a completely filled valence shell

D) electrons fill orbitals singly and with similar spin before pairing

Answer 1

Hund's Rule states that electrons fill orbitals singly and with similar spin before pairing. It helps determine the electron configuration of atoms and molecules.

Step-by-step explanation:

Hund's Rule states that electrons fill orbitals singly and with similar spin before pairing. This means that when filling orbitals with electrons, each orbital will be occupied by one electron before any orbital is occupied by a second electron. Additionally, all of the single electrons must have the same spin. Hund's Rule helps to minimize repulsive forces between electrons and determine the electron configuration of atoms and molecules.
