Yes, noble gases have a complete octet in their valence shell, which means they possess a full set of eight electrons in their outermost energy level. This full octet configuration makes them generally unreactive, as they do not readily lose, gain, or share electrons. The stability of their electron configuration is the reason why noble gases are often found in nature as monatomic gases.
What else can I help you with?
Why is a filled valence shell often called an octet?
A filled valence shell often has 8 electrons, which is called an octet. This configuration is considered stable because it mimics the electron configuration of noble gases, which have full valence shells.
What is the rectivity of the noble gases in terms of valence electrons?
Noble gases are also known as the inert gases, meaning they don't react because they have a stable octet (eight electrons in their valence shell). They all have eight electrons in their valence shell with the exception of helium because helium is rebel, but they are all nonreactive including helium.
How many valence electrons are present in noble gases?
Noble gases do not like giving up electrons. There are 2 electrons in the outer shell of helium and 8 electrons in the outer shell of the other noble gases (group 18 of the periodic table), representing filled shells.
What is the outer shell of the noble gases called?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
How many electrons are present in the valence level for all noble gases except helium?
There are 8 electrons present in the valence level for all noble gases except helium. This is because in the outermost shell, known as the valence shell, noble gases (excluding helium) have a full octet of electrons, making them stable and unreactive.
Which families contains a full octet of valence electrons?
These are the noble gases.
Why is a filled valence shell often called an octet?
A filled valence shell often has 8 electrons, which is called an octet. This configuration is considered stable because it mimics the electron configuration of noble gases, which have full valence shells.
The nonreactive elements at the far right of the periodic table that contain an octet of electrons in their valence shell are?
D. Noble Gases

What family has complete octet of valence electrons?
The noble gases have a complete octet of valence electrons. This means they have a full outer electron shell, which makes them stable and less likely to react with other elements. Examples of noble gases include helium, neon, and argon.
What is the outer shell of the noble gases called?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
How do the gases differ from the other elements?
Noble gases differ because they obtain a full valence electrons of 8 on the outer shell. OCTET RULE: states that every element aspires to be a noble gas and have a full valence level.
How many electrons are present in the valence level for all noble gases except helium?
There are 8 electrons present in the valence level for all noble gases except helium. This is because in the outermost shell, known as the valence shell, noble gases (excluding helium) have a full octet of electrons, making them stable and unreactive.
Has Eight electrons in a valence shell?
These are the noble gases which have a complete valence shell.
What is the term use for a completed outer shell of 8 electrons?
The most common term for a completed outer shell of electrons is that is or has "full" valence electrons.
How many electrons are in the outer shell of Ar?
Argon has eight valence (outer) shell electrons. It is a Noble Gas so its valence shell is full (Octet Rule).
