An atom is stable if it does not undergo decay.
A stable atom is one that is free from any detectable rate of radioactive decay.
The atomic number equals the number of protons in an atom, as well as the number of electrons in a stable, electrically neutral atom, it represents the identity of an element ,the simplest form of matter.
According to Madelung rule the no. of electrons filled in a shell or orbit depends on the energy of shell or orbit . lower is the energy of shell higher will be its priority for electron filling. 1st orbit can have 2 electrons 2nd orbit can have 8 electrons 3rd orbit can have 18 electrons 4th one can have 32 electrons and so on. These are the most stable configurations of atoms. it seems that only electrons are responsible for atom's stability, because they are present outside nucleus of atom and take part in the chemical reaction. As it is natural fact that every object in this world try to attain stability, the same principle applies on the stability of atom. if an atom have 5 electrons it will either try to gain 3 more electrons or try to lose 3 electrons as it will try to attain the most stable configuration as it is given above. Only after attaining the stable configuration, the atom will be inert i.e.it will not react.
The numbers of protons and neutrons in its nucleus, and the number of electrons in its valence shell. The number of protons and neutrons will affect the element and the isotope number, some isotopes are stable, some are not. Atoms are also more stable with a full outer energy level (octet rule - 8 electrons in the outermost shell).
An atom is stable (i.e. non-reactive) when it's valence orbitals are full. An orbital is essentially an available place for an electron to orbit (or the shape of the electron 'cloud' in quantum models). The 'valence' orbital is the outside orbital of that particular atom. Atoms form stable compounds when they can share electrons to mutual advantage. For example, carbon has only 2 electrons in its valence orbitals, but has room for 6. Therefore, carbon is stable when it can form a compound with something that will let it share share 4 electrons.
According to The Secret, Yes. An Atom does contain energy. every thing that can move contains energy known as Kinetic Energy.
Yes, Chlorine atom is stable
A completley filled out electron level makes the atom stable
An atom becomes stable by gaining or loosing 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.
Those atoms which are not radiatin alfa, beta or gama rays r cald stabl atoms
