Yes, the stability of noble gas elements other than helium is due to their having eight valence electrons. This electron configuration, known as an octet, gives them a full outer energy level, making them highly stable and less likely to form chemical bonds with other elements.

Why elements tend to attain stability?
Except for the noble gases, the atoms of all elements are unstable. This is why they form molecules and compounds, in order to become stable. Stable means having the same valence configuration as a noble gas. For all but the first two elements that means having an octet (8) of electrons in their valence shells after chemical bonding.
How do valence electrons tell you what elements will bond together?
Atoms only bond if it helps them achieve their goals of having 8 valence electrons. That is why noble gases do not bond; they already have 8 valence electrons.
How is the reactivity of a element releated to the outer shell?
The outer, or valence shell of electrons is closely related to an element's reactivity. First of all, the valence electrons are the only part of an atom that participate in a chemical reaction. The closer an atom's number of valence electrons is to eight (remember the octet rule), the more reactive it typically is. Elements with only 1 valence electron* (group 1) and elements with 7 valence electrons (group 17) are the most reactive. *Remember, having only 1 valence electron means once you lose it, you now have 8 electrons that were in the shell below it.*
Why do atoms with a weak electronegativity like lithium have a weak attractive force for electrons?
they have few valence electrons and aren't close to having eight valence electrons
Why do properties of element change in Regular way across a period?
As atomic number increases, the number of electrons also increases except for Period 1 because it ends with a number of valence electrons with higher energy , (This pattern means that the elements within a group always have the same number of valence electrons having the result of having similar properties.)

What is the purpose of elements to lose or gain valence electrons to become an ion?
they want to become stable by having all of the valence filled they want to become stable by having all of the valence filled
Which compounds are tetravalent?
Tetravalent means having 4 valence electrons. The elements in the 14th group are tetravalent. They do not lose or gain electrons. they gain electrons.
Inert gas having 8 valence electrons?
mercury is an inert gas having 8 valence electrons
How many electrons does valence have?
Answer:According to the octet rule, there can be a max of 8 electrons in one energy level, including the valenceAnswer:The maximum number of electrons per orbitals = 2p = 6d = 10f = 14The number of valence electrons can be determined by looking at the periodic table.
How can you use a periodic table to predict the number of valence electrons an element has without having to draw the Bohr diagram?
In general, except for the transition elements, the group number will tell you the number of valence electrons. For example, Na is in group 1 and has 1 valence electron. Cl is in group 7 and has 7 valence electrons.

Do valence electrons affect the reactivity of an element?
atoms are most stable when they have filled the outer shell of electrons which normally holds a max of 8. so if an atom has 1 electron in its outer layer getting rid of it will give him stability, in much the same way having 7 electrons will mean gaining one electron will give it stability. now lets say the two meet, they react with each other and everybody is happy. It is thought than when two elements react, they are trying to acheive a "perfect" electronic configuration (i.e. have a full outer shell). The more electrons needs to lose/gain before acheiving this stability determines its reactivity.
Are having eight valence electrons makes atoms very reactive?
No, eight valence electrons completely fills the valence band and makes the atom inert. The most reactive atoms have either one valence electron or seven valence electrons.
What kind of elements has less than 4 valence electrons?
Boron group, transition metals, alkaline earth metals and alkali metals are listed in the Periodic Table are having less than four valence electrons
Why do atoms with a weak electronegativity like lithium have a weak attractive force for electrons?
they have few valence electrons and aren't close to having eight valence electrons
