An atom becomes stable by gaining or loosing electrons.
Yes, Chlorine atom is stable
An atom is stable if it does not undergo decay.
A completley filled out electron level makes the atom stable
If an atom has more protons then electrons the atom will have a negative charge.If the atom has more electrons then protons the atom will have a positive charge.If the atom has equal numbers of electrons and protons then the atom becomes neutral.However if you're wondering why an atom is stable then that means that it has all the electrons inside of it paired. If the atom is unstable it has unpaired electrons.
Having an equal number of anything does not make an atom stable.
hydried is more stable than H-atom
yes it is stable
It is stable when filled with electrons.
A stable sodium atom has 11 electrons.
When the atom has 8 valence electrons.
An atom must be stable because it must not react with other atoms to change it's state.
yes that is true, it does make up an atom stable.
