How many valence electrons do noble gases have and explain why they are very unreactive with other elements?
There are six noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

How many valence electrons will result in chemical stability for an atom?
A full outer shell of electrons typically results in chemical stability for an atom. This corresponds to 8 valence electrons for most atoms (except hydrogen and helium, which only need 2 valence electrons for stability).
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
What are valence electrons and how do they relate to the noble gases?
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
What are valence electrons for responsible for?
Valence electrons are responsible for chemical boding.
How many valence elactrons do all the elements in neon's family have?
8 valence electrons are there in in neon's family .They are stable in nature.
How many valence electrons do transitions elements have?
How many valence electrons do transition elements have?
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).

The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Is a noble gas an unreactive gas?
Yes, they are. The noble gases (group 18) on the periodic table of elements are unreactive because they have 8 electrons on their outer shell (valence electrons) and therefore they are very stable. Due to this stability, they will rarely react with any other chemical.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.

Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
Which group contains eight valence electrons?
Group 18 contains eight valence electrons, namely the noble gases.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
What does the group of A elements tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
What are valence electrons for responsible for?
Valence electrons are responsible for chemical boding.
