Answer When the outermost shell(valence shell) is filled the atom is to be most stable.

First Shell: holds up to 2 electrons

Second Shell: holds up to 8 electrons

Third Shell: holds up to 18 electrons

Fourth Shell: holds up to 32 electrons

Atoms are most stable when the outer most ring has 8 electrons and the

number of electrons are equal to number of protons.

An atom is most stable when its outer electron shell is full, typically containing 8 electrons. Atoms will try to gain, lose, or share electrons to achieve a full outer shell and become more stable.

An atom can be chemically stable when its electrons shell is full. For many elements, this means having 8 electrons in their outer levels, while a couple of them need at least two.

It becomes most stable when its nucleus is filled, not when it is filling it.


What is the most stable state of an atom called?

The most stable state of an atom is called the ground state. This is when the electrons occupy the lowest energy levels available to them.

What causes an atom to be stable?

An atom becomes stable by gaining or loosing electrons.


What will an atom of iodine most likely do to be stable?

An atom of iodine will most likely gain one electron to form a stable octet in its outer energy level. This will give iodine a full set of 8 electrons, making it more stable and less likely to react with other atoms.


What electorns configuration represents the most chemically stable atom?

The electron configuration that represents the most chemically stable atom is the noble gas configuration, which is when an atom has a completely filled valence shell. This configuration is stable because it has a full complement of electrons and is unlikely to gain or lose electrons.

An atom with it's electrons in the lowest possible energy level is said to be?

An atom with its electrons in the lowest possible energy level is said to be in its ground state. The ground state is the most stable configuration for an atom, with electrons occupying the available energy levels starting from the lowest.
