The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the Periodic Table.
The noble gases with 8 valence electrons are the most stable group.
how many electrons do the elements of the most stable group have in their outer energy level?
Most need 8 electrons in the valence shell. :)
In the short form: elements are striving to completely fill valence shells of electrons to reach a quantumly stable energy state. They react to take electrons away from elements willing to give up electrons or share outer shell electrons with elements they aren't strong enough to steal from.
Ionization energy is the energy required to remove an electron from an atom. In the case of hydrogen, its one and only electron is very close to the nucleus, because it is in the first energy level (that electron's ground state.) So, the attraction between the nucleus (positive) and that electron (negative) is quite strong due to their closeness. As you move down group 1, the electrons get farther and farther away from the nucleus, and the attraction, predictably, decreases. This means lower ionization energy required the lower you go on the group.
Most of the noble gases have 8 electrons in their outer shell, but helium has only 2, and is the most stable of all elements.
Elements in Group 18 already have an octet of electrons, which is a full outer shell of 8 electrons. An octet of electrons makes the element stable, so it does not need to react with any other elements to gain or lose electrons.
it can be stable by completing their octet & minimizing their energy
Group 18 elements have a stable octet.
Group 8
They r noble gases which have stable valance shell and grotp no. 18
Some elements are stable on their own because they have a complete outer energy level. These elements are called noble gases. Hydrogen and Helium have a complete energy level with two electrons and all of the other elements are stable with eight. When an element doesn't have a complete outer energy level it is stable in a compound. This is because it is being combined with another element to complete it's energy level.
The elements can only be stable when it complete is octate in its outer most orbit has 8 electrons in its outer most orbit by gaining or losing energy

They r noble gases which have stable valance shell and grotp no. 18
yes
Elements get stable only when it completes electron octate in its outermost orbit. Elements make compounds with other elements to gain or reduce electrons to get stability. silicon make bonds with oxygen and make silicon dioxide to get stable.

Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
The inert or noble gases have a stable full outer shell of electrons which is why they are so unreactive.
