Natural systems left to themselves move towards states of lower potential energy. For example, water flows down a hill or a ball rolls down a hill, if free to do so. States of lower potential energy are more stable. As a rule, the lower the potential energy of a system, the more stable it is. As a result, left to themselves, systems attempt to reach the configuration with the lowest energy possible under a given set of constraints. To change the state of a system from lower to higher potential energy, one must therefore supply energy to the system.
A completley filled out electron level makes the atom stable
A stable atom with 90 neutrons could potentially have a maximum of 90 protons, as the number of protons would have to be equal to or less than the number of neutrons for the atom to be stable.
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.
An atom will give up an electron when it is more stable by achieving a full outer electron shell. This typically occurs when the atom is in an ionic bond or is trying to achieve a more stable electron configuration.
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.
Atom in the ground state is stable but atom in excited state is not stable the main reason for this is their energies.Atoms in excited state has more energy so they undergo chemical reaction so they are not stable but atoms in ground state has less energy than the excited state so they dont undergo chemical reaction.
less stable
A completley filled out electron level makes the atom stable
Valence electron are found in the outer shell of an atom. Depending on the number of valence electrons, the atom is more or less stable: fewer => less stable and more => more stable (inert). Stable = less likely to react with other atoms.
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.
Sort of... The general tendency is for a larger atom to be less stable. Above a certain point (after lead) no stable atoms are known to exist.Sort of...

The most stable atom is helium because it has a full outer electron shell, which makes it less likely to react with other atoms.
Because it is already stable!

chlorine is a group seven element with outmost energy level lacking only one electron, thus is not stable. when it gains this electron, it gets an octet electron structure(8 e in the vallency shell) this makes it very stable in the enviroment; the reason why chlorine molecule exists due to its stable atoms but chlorine atom does not exist in nature
the lowest energy level occupied by an electron when an atom is in its most stable energy state
When all electrons in an atom are in orbitals with the lowest possible energy, the atom is in its ground state. This is the most stable arrangement for the electrons in an atom.
