What type of element is most stable and chemically inactive?

Answer 1

It can be chemically inactive if the outer electron shell, or ring, has 8 electrons on it. For example, most of the noble gases have 8 electrons on the outer electron shell, such as neon.

I think...

It really is when the outer shell of the atom is complete:

In case of the first shell it would need 2electrons to be complete.

In case of the second shell it would need 8 electrons to be complete.

In case of the third shell it would need 18 electrons to be complete.

In case of the fourth shell it would need 32 electrons to be complete.

that's what I think it is. Hope it's useful ! :)

Answer 2

The reason some elements are chemically inert is that their outer electron shell, the valence shell, is full. It is the action of the valence shell electrons that determine chemical bonding possibilities. You'll recall that bonding is the electrons' way of filling a shell by borrowing an electron or a couple or three to fill a shell, or loaning out an electron or a couple or three to end up with a full outer shell. And all this happens because atoms tend to be "happiest" with a full outer electron shell. If an element already has a full valence shell, it isn't interested in loaning or borrowing electrons. That element is an inert or noble gas, like helium, neon, argon, krypton, xenon or radon. These are all the elements in Group 18 of the Periodic Table.

Answer 3

The inert elements, called the noble gases, which are in group 18 have their valence shells filled. Atoms react with one another in order to achieve filled valence shells, either by sharing or transferring valence electrons. Since the noble gases' valence shells are already filled, they do not react.

Answer 4

Noble gases are the most stable and chemically inactive elements due to having a full valence electron shell, making them less likely to form chemical bonds with other elements. Examples of noble gases include helium, neon, and argon.

Answer 5

Nothing is chemically inactive but noble gases are least reactive elements.

Answer 6

The electron configuration is responsible for this. If the elements have a stable electron configuration, they become inert.

Answer 7

The noble gases which have an octet of outer electrons are most stable and tend to be relatively inactive.

Answer 8

It would be a noble gas.
