How many Valence electrons in a stable octet?
8 valence electrons
How many valence electrons do stable atoms have?
A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)
Are elements with 8 outer electrons stable?
yes
How many electrons of the most stable have in there outer energy level?
The most stable atoms/ions have 8 electrons in their outermost shell.
How many valence electrons will result in chemical stability for an atom?
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.
How does a atom become stable?
When the atom has 8 valence electrons.
How many valence electrons are in a stable nonmetal ion?
8
An element is stable with eight electrons in its?
Oxygen (O) has 8 protons and 8 electrons.
When an atom or an ion has 8 valence electrons it is more or less stable than when it ha fewer than eight valence electrons?
Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
Does an atom need 8 electrons in its outer shell to be stable?
YES!
What is the number of electrons in the most stable outer shells?
This number is 8.
