The most stable number of valence electrons is 2 for hydrogen and helium, which have only one electron shell in the shell model for atomic electron configurations, and 8 for all other elements.

Where are valence electrons found?

Valence Electrons are the electrons that are located furthest away from the atom itself in the outermost electron shell. They are located on the last energy level also known as the valence level.

How many valence electrons do stable atoms have?

Oh, dude, stable atoms typically have 8 valence electrons because they want to be all balanced and happy. It's like they're throwing a party and they need 8 cool electrons to join in on the fun. So yeah, 8 valence electrons is the magic number for stable atoms.


How many valence electrons do most elements need to become stable?

8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.


What are the electrons in the outer most energy level of an atom called?

The electrons in the outermost energy level of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to achieve a stable configuration.


How many valence electrons do most atoms need to have a complete outer Shell and be happy?

Most atoms need eight valence electrons to have a complete outer shell and achieve a stable, "happy" state, a concept known as the octet rule. However, there are exceptions, such as hydrogen and helium, which are stable with just two valence electrons. Atoms tend to gain, lose, or share electrons to reach this stable configuration.


Most atoms need eight valence electrons to be stable is called what?

Octet Rule!
