The number of electron shells depends on the noble gas. The number of shells will be equal to the period in which the noble gas is present.
Not much. Noble gases have full valence shells, or full outermost shells, so they don't tend to bond with many other elements. They are also the most stable of all the element families.
The Noble Gases are so-called because they do not readily react chemically with anything, due to their valence electron shells being filled with 8 electrons. The exception, of course, is helium, He, which only has 2.
Alkali metals have one electron more than the noble gases.
The gases used in many light bulbs, such as argon and krypton, are highly unreactive and belong to the noble gases group in the periodic table. This group is located in the far right column, specifically in Group 18. Noble gases are characterized by their full valence electron shells, which contribute to their chemical stability and low reactivity.
They have 8 electrons on the outermost shell, also known as valence.
Xenon has 8 electrons in its outer shell. It belongs to Group 18 of the periodic table, known as the noble gases, which have full outer electron shells.
Noble gases have 8 electron shielding layers. This is because noble gases have a full outer electron shell, so they have filled all available energy levels up to the 8th shell, leading to 8 electron shielding layers.
any time there are as many electrons and protons and they fill each orbital optimally.
The Noble Gases are so-called because they do not readily react chemically with anything, due to their valence electron shells being filled with 8 electrons. The exception, of course, is helium, He, which only has 2.
Bromine has 4 electron shells.
Polonium has 6 electron shells.
Magnesium has three electron shells. The electron configuration is 2,8,2
