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.

What is the importance of an atom having a noble gas configuration?
They are generally stable as they obey octet rule
Noble gases have a set of eight outermost electrons which forms what?
It forms an octet / stable electronic configuration
The octet rule is the tendency to have electrons in the shell after ion formation or bond formation?
The octet rule is the tendency to have eight electrons in the shell after ion or bond formation.. This gives the same configuration as a noble gas.
How many valence electrons in kypton?
Krypton has 8 valence electrons that is 4s2 4p6.it is chemically inert since it attains an octet configuration.
Explain what atoms are trying to achieve in there electron shells when they bond with each outher?
Atoms are trying achieve a stable electronic configuration i.e., stable arrangement of electrons in their electron shells. All configurations are not stable. Mostly stable configuration is attained by forming an octet of electrons in outer most shell. Sometimes octet rule is violated also.
Why are bonds form?
They are formed to attain a balance octet configuration
How does the octet rule explain the formation of a sodium ion?
Na atom ion has an electronic configuration 2,8,1 On losing one electron it forms Na+ cation, with the configuration of 2,8 thereby obeying octet rule.
Do Ionic share or transfer electrons?
To achieve octet configuration (stable)
How does sodium obey the octet rule when reacting to form products?
When sodium loses its single valence electron, it achieves the noble gas configuration of neon, which is an octet.
What is the importance of an atom having a noble gas configuration?
They are generally stable as they obey octet rule
How does the compound LiF Violate the octet rule?
Lithium electron configuration: 1s2 2s1, or in shorthand: [He] 2s1 Thus in LiF the Li cation (Li missing one electron to get its nobel gas configuration of He) it is Li+: 1s2 2s0, or in shorthand: [He] 2s0, This ion does NOT have 8 (octet) electrons, although it has a nobel gas configuration of He: 1s2.
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 do you mean by octet and duplet?
In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.
Noble gases have a set of eight outermost electrons which forms what?
It forms an octet / stable electronic configuration
What is a pseudo-noble gas?
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
Does lithium follow the octet rule?
Sort of. Lithium loses one electron in order to achieve the noble gas configuration of helium, which has only two valence electrons in its 1s sublevel. The octet rule refers to the fact that atoms share or transfer electrons in order to achieve a noble gas configuration with eight valence electrons, called an octet. Helium is an exception to the rule.
What is the statement of an atom when most stable when it has eight electrons in its outermost energy level?
One of these choices are your ansewr: * Octave * Balance * Valance * Octet
