The octet rule is a basic way to determine if the atoms involved in a covalent molecule have enough electrons to fill their valence shells. It simply says that each atom must be able to "reach" a total of 8 electrons to be full. There are many exceptions, due to it not being an entirely true rule.

∙ 9y agoThe octet is a stable configuration in the noble gases and generally elemnts in group 1,2, 13 14 15 16 17 add or lose electrons or share electrons to achieve this. There are exceptions- the boron trihalides have only 6 electrons in three single bonds. The octet rule does not apply to hydrogen this shares an electron to achieve the electron config. of helium.

How is the octet rule used in covalent bonding?
look for it on the chemistry book, and don't be lazy!Covalent bonding is all about "sharing electrons" so the two elements share electrons (which forms a covalent bond) in order to complete or help complete their octet.
What rule is used to determine how many covalent bonds an element can form?
The number of Covalent Bonds is equal to eight minus the group number.
Why are electrons shared in covalent compounds?
electorons are shared in covalent compounds, because covalent compounds occur between nonmetals elements.
How are the duet and octet rules used to describe the arrangement of electrons in a molecule?
The very simple duet and octet models of covalent chemical bonding describe the chemical bond as involving an electron pair situated between atoms and that atoms lighter than He (there is only H!) achieve a stable duet (2 electrons)-- atoms heavier than He achieve an octet. the duet and octet are the stable configurations of noble gases. Lewis dot diagrams are typically used to "place" the electrons in the appropriate positions.
When was the octet rule invented?
Although it was a slow process involving numerous years of research and chemists, in 1919 Irving Langmuir refined the concept into the cubical octet atom and octet theory. This octet theory evolved into what is now known as the octet rule.

What are the uses of a covalent bonding?
covalent bonding is used to share electrons
What is the octet rule and how is it used in Lewis dot structure?
Most elements have a stable electron arrangement when they have 8 electrons in their outer shell (hydrogen and helium are exceptions, they are stable with only 2 electrons in their outer shell), and an octet is 8 of something, hence the octet rule. Lewis dot diagrams are drawn to show how many electrons are associated with any given atom, and how the atoms are shared, in the case of covalent bonding. Generally, each atom winds up with 8 electrons. Not hydrogen.
What type of bonding involves the sharing of electrons?
Covalent bonding.

electorons are shared in covalent compounds, because covalent compounds occur between nonmetals elements.

What is the term used when two or more atoms share electrons?
This is called covalent bonding.
What are two types of bonding's?
There are actually 3 types of chemical bonding- Ionic bonding, covalent bonding and metallic bonding.
How is EN used in determining the ionic or covalent character of the bonding between two elements?
Usually ionic compounds are electronegative.
What part of an atom is important in bonding?
The part of the atom that is used in bonding is the electron. More specifically, valance electrons which are the outer shell of the electron.
