What does the atomic number of an atom represent?
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.
When would an atom be chemically stable not react?
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.
What determines the stability or reactivity of an atom?
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).
How do the atoms in molecular compounds form stable electron arrangements?
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.
Does an atom's nucleus hold a large amount of kinetic energy?
According to The Secret, Yes. An Atom does contain energy. every thing that can move contains energy known as Kinetic Energy.
Is chlorine atom stable?
Yes, Chlorine atom is stable
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
Is the Atomic number of 7 a stable atom?
yes it is stable
An atom is stable when its outermost orbit is?
It is stable when filled with electrons.
How many electrons does a stable sodium atom have?
A stable sodium atom has 11 electrons.
How does a atom become stable?
When the atom has 8 valence electrons.
Why does an atom want to be stable?
An atom must be stable because it must not react with other atoms to change it's state.
Does a partially filled outer electron level make an atom stable?
yes that is true, it does make up an atom stable.
What atom is a stable atom?
Those atoms which are not radiatin alfa, beta or gama rays r cald stabl atoms
