All atoms want to have their outer energy levels full. When they have eight valence electrons they are full. They will become full by combining with other elements that the they may encounter until they see eight. You also could say until they have eight valence electrons.

∙ 12y agoThe octet rule states that atoms prefer to have 8 valence electrons. However, there are many exceptions, and it does not apply to transition metals.

∙ 10y agoHaving eight valence electrons makes an atom stable, with the exception of helium, which is stable with only two valence electrons
Wiki User
∙ 9y agoFor a good deal of organic chemistry relevant atoms, having a shell with 8 electrons is the most energetically favorable.

What rule states that to be stable atoms need 2 valence electrons?
This rule doesn't exist; you think probable to octet rule.
What The octet rule is satisfied when two atoms acquire how many valence electrons?
Eight
Why is the noble gas group the most stable group?
According to the Octet Rule, the most valence electrons any atom can have is 8. Atoms naturally want to meet this rule either by losing or gaining enough electrons to have a total of 8 valence electrons. The nobel gases have exactly 8 valence electrons. The neither need to lose or gain any and therefore do not play well with others. The losing or gaining of valence electrons determines the stability and reactivity of the element.
What role do valence electrons play in the formation of compound from elements?
Valence electrons are the electrons on the outer most shell of a neutral atom; they are used when forming chemical bonds with other atoms. Because of the octet rule - which is a chemical bonding theory based on the assumption that in the formation of compounds, atoms exhibit a tendency for their valence shells to either be empty or a full 8 electrons (octet) - atoms that do not have an octet need to either get rid of their electrons or gain more electrons. Atoms combine with other atoms in order to stabilize themselves. For example if sodium and chlorine were to combine sodium would need to lose 1 valence electron while chlorine would need to gain 1 valence electron. Na + Cl ------> NaCl FYI NaCl, sodium chloride, is table salt. *NB* All elements react in order to become stable and either get an octet or empty their shell. They are all attempting to be like the noble gases, which are hellium, neon, argon, krypton..etc. FYI noble gases are all stable and have 8 valence electrons.
Do you always follow the octet rule when drawing a Lewis structure?
Yes, because all atoms must have 8 electrons around it. (Full valence orbital)
Most atoms need eight valence electrons to be stable is called what?
Octet Rule!
What rule states that to be stable atoms need 2 valence electrons?
This rule doesn't exist; you think probable to octet rule.
What The octet rule is satisfied when two atoms acquire how many valence electrons?
Eight
What is the duet rule?
OCTET RULE:-The tendency of atoms to require eigth electron configuration in their valence shell, when bonding,is called octet rule.DUPLET RULE:-The tendency of atoms to require two electron configuration in their valence shell, when bonding,is called duplet rule
What states that atoms tend to gain lose or share electrons in order to achieve a full set of valence electrons typically?
The octet rule.
Why do most element have a characteristics valence?
Valency depends upon no of electrons in outer most shell the atoms have a specific no of electrons in valence shell so they have characteristic valence .(but transition metal violate this rule).
Why is the noble gas group the most stable group?
According to the Octet Rule, the most valence electrons any atom can have is 8. Atoms naturally want to meet this rule either by losing or gaining enough electrons to have a total of 8 valence electrons. The nobel gases have exactly 8 valence electrons. The neither need to lose or gain any and therefore do not play well with others. The losing or gaining of valence electrons determines the stability and reactivity of the element.
What is the name when atoms have eight valence electrons in order to be stable?
They call that the octet rule, but it isn't really a "rule".
What is the rule?
atoms either loose or gain a maximum of 2 valence electrons like hydrogen
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)
Does ClF5 obey octet rule?
Yes. Both O-F bonds are single covalent, so all three atoms can claim 8 electrons.
What does the rule of 8 mean for the periodic table?
Atoms with 8 valence electrons (or obeying octet rule) have more stability and are generally chemically inert.
