What is the duet rule?
Understand the Problem
The question is asking for an explanation of the duet rule, which is likely referring to a concept in chemistry related to the stability of atoms in molecules. The duet rule states that certain elements, particularly hydrogen and helium, are stable when they have two electrons in their valence shell, resembling the electron configuration of helium.
Answer
The duet rule states that hydrogen and helium atoms are most stable with two valence electrons.
The duet rule states that hydrogen and helium atoms are most stable with only two electrons in their valence shell.
Answer for screen readers
The duet rule states that hydrogen and helium atoms are most stable with only two electrons in their valence shell.
More Information
The duet rule is particularly applicable to the first two elements in the periodic table, hydrogen and helium, because their valence shells can only hold a maximum of two electrons.
