What is octet configuration?
Octet configuration refers to how elements generally prefer to form bonds so as to attain an octet configuration, i.e. have 8 electrons in their valence shell. For example, chlorine (Cl) is from Group VII and has 7 valence electrons. It will gain one electron (eg from sodium which loses one electron to form Na+) to form Cl-, which has 8 valence electrons and so fulfills the octet rule and is stable. The electronic configuration of sodium is 2.8.1 (if you're in secondary school), or 1s2,2s2,2p6,3s1 (more advanced). So by losing one electron to form Na+, sodium also attains octet configuration.
How many electrons does lithium need to add to satisfy the Octet Rule?
Seven electrons should be added to attain the higher noble gas configuration.
Why does aluminium chloride have a low melting point?
Maybe because aluminum atom in Alcl3 does not attain octet arrangement... thus, it undergoes dimerisation to produce al2cl6, where the aluminum atom achieve an octet electronic configuration.
Why do the halogens in group 7a have such high electron in affinities?
Mostly they are highly electronegative and they only need one electron to fill their outer shell in a noble gas octet configuration.
An octet is equal to?
The octet rule is a simple chemical rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electronic configuration as a noble gas. The rule is applicable to the main-group elements, especially carbon, nitrogen, oxygen, and the halogens, but also to metals such as sodium or magnesium. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons.
Why are bonds form?
They are formed to attain a balance octet configuration

Why does chlorine want to gain 1 electron?
Generally, atoms would want to fulfill the octet rule: 8 electrons in the valence shell. This gives the atom a noble gas configuration and is seen as stable. Since the Chlorine atom is in group 7 of the periodic table, it "prefers" to gain one electron instead of losing 7 to attain the stable octet configuration.
How many electrons does lithium need to add to satisfy the Octet Rule?
Seven electrons should be added to attain the higher noble gas configuration.
How many electrons does lithium lose or gain to achieve a stable octet configuration?
Lithium is in group 1 of the Periodic How_many_electrons_must_the_lithium_atom_give_up_to_become_stable, so it must lose one electron for it to attain a full outermost energy level and become stable.The charge will then be positive (+).
How many electrons do all halogen family elements need to gain in order to attain a noble gas configuration?
They need 7 more to complete the octet.
How many more electrons does chloride need in order to have a noble gas configuration?
chlorine would need only one electron to attain an octet structure.
Why do certain atoms react with other atoms?
since not all atoms have same no.of electronic configuration they try to attain an octet sharing electrons each other
What is the Electron configuration for the argon atom?
The electronic configuration of Argon (Ar) is - 8,8,8 because its in group 8 and is inert because it has a full octet. Happy to help ;)
What are 8 singers called?
A group of eight anything is called an "octet".
What is a molar mass of atomic oxygen?
One oxygen atom by itself is written as O. Molecular oxygen is a molecule of two oxygen atoms that are covalently bonded. The atoms both attain the stable octet configuration.
Is octet a collective noun?
The noun 'octet' is a word for a group of eight. The noun 'octet' is not a standard collective noun for a specific group, but can be used as a collective noun for any group of eight; for example, an octet of singers, an octet of swans, etc.
