The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
What else can I help you with?
Why are what octet's rule?
Octet Rule: In order for atoms to become more stable, they will take electrons, lose electrons, or share electrons so that their outer shell/level will contain eight electrons and be complete.
How many does the atoms electrons in their outer shells does the Octet Rule state they need?
The Octet rule is for eight(8) electrons in the outer most energy shell. NB Remember 'Octa' from Latin , means '8' ( eight).
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.
Which rule says that elements will bond to a total number of 8 electrons to be stable?
octet rule
What is octet rule and give two examples which do not follow this rule?
The octet rule is a rule in chemistry where elements want to form bonds to attain 8 electrons in their valence shell. An example of this would be sodium chloride. Bonds that don't have 8 electrons in their valence shell don't follow this rule
What rule states that to be stable atoms need 2 valence electrons?
This rule doesn't exist; you think probable to octet rule.
Octet rule for diatomic elements?
In diatomic elements, such as hydrogen (H2) or oxygen (O2), each atom follows the octet rule by sharing electrons to achieve a stable electron configuration. This results in a full outer shell of electrons with a total of 8 electrons, satisfying the octet rule. The sharing of electrons allows the diatomic molecule to be stable.
What does the hund's rule states?
Hund's Rule states that electrons will occupy orbitals of a subshell singly before any are doubly occupied. This is to maximize the total spin of the electrons in the subshell.
What would be the charge on a carbon ion that obeys the octet rule?
A carbon ion that obeys the octet rule typically has a charge of 4-. This is because carbon has four valence electrons and typically gains four electrons to achieve a full valence shell of eight electrons, conforming to the octet rule.
How many electrons does strontium lose to satisfy the octet rule?
Strontium typically loses 2 electrons to satisfy the octet rule. Since strontium is in group 2 of the periodic table, it has 2 valence electrons. By losing these two electrons, it attains a stable electron configuration similar to a noble gas.
Which rule is violated in the configuration of 1s2 2s2 2px2?
Hund's rule is violated in this configuration. According to Hund's rule, electrons will fill empty orbitals before pairing up in the same orbital. In this case, the electrons should have filled the 2py and 2pz orbitals first before pairing up in the 2px orbital.
Is PF5 an exception to the Lewis octet rule?
Yes, PF5 is an exception to the Lewis octet rule. Phosphorus has 10 electrons around it in PF5, exceeding the octet rule. This is due to the availability of d-orbitals in the valence shell of phosphorus for accommodating extra electrons.
