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

number of electrons are equal to number of protons.

∙ 9y agoAn 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.

What will an atom of iodine most likely do to be stable?
Steal an electron from an atom of a different element.
How many electrons are called are needed in the outer energy level of most atoms for the atom to be stable?
Eight electrons, called an octet, are needed by most atoms in order to be stable.
How many number neutrons magnesium?
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
Does a partially filled outer electron level make an atom stable?
yes that is true, it does make up an atom stable.
What makes the most stable atom?
Probably cesium fluoride, since it combines the least electronegative (non-radioactive) element with the most electronegative one.
Is iron the most stable atom?
True
What will an atom of iodine most likely do to be stable?
Steal an electron from an atom of a different element.
Does an atom become most stable when trying to fill its nucleus?
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 ground state.
Is chlorine atom stable?
Yes, Chlorine atom is stable
Is the most atom more or less stable when they have eight valence electrons true or false?
less stable
What is an atom stable?
An atom is stable if it does not undergo decay.
What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
What causes an atom to be stable?
An atom becomes stable by gaining or loosing electrons.
A stable atom has equal numbers of?
Having an equal number of anything does not make an atom stable.
Is hydride ion more stable or less stable than H-atom?
hydried is more stable than H-atom
A bromine atom would form its most stable ion by?
gaining 1 electron
