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 else can I help you with?
What is an atom stable?
An atom is stable when it has a full outer electron shell, which typically consists of 8 electrons. Atoms can achieve stability by gaining, losing, or sharing electrons through chemical bonds. Stable atoms do not easily react with other atoms or lose their structure.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
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.
The reactivity of an atom arises from what?
The reactivity of an atom arises from its electron configuration. Atoms with incomplete outer electron shells are more reactive as they tend to gain, lose, or share electrons to achieve a stable electron configuration. This behavior is driven by the atom's desire to reach a more stable state, typically following the octet rule.
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).
What is formed when a sodium atom and a chlorine atom react chemically?
study
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
What type of bond would be formed between a carbon atom and a helium atom?
Helium will not react with carbon as helium is chemically inert.
What is formed when a sodium atom and chlorine atom react chemically?
When a sodium atom and a chlorine atom react chemically, they form an ionic compound called sodium chloride (NaCl), commonly known as table salt. Sodium donates an electron to chlorine, forming a positively charged sodium ion and a negatively charged chloride ion, which are attracted to each other and form a stable compound.
How the number of electrons in an energy level affect bond formation?
If the atom is chemically stable it doesnt need to bond, it is chemically stable when the outermost level is completely full of electrons
Why won't stable elements react?
Stable elements do not react because they don't need to. Elements react so that they can gain stability( as stability is gained by filling the outer most shell of the atom). As stable elements already have full outer shells and are stable , they do not react.
What makes atoms have a stable electron configuration?
In order for an atom to be chemically stable it must have 8 valence electrons.
Are the atom is chemically stable when its outer energy level contains all the electrons it can hold?
yes
An atom is chemically stable when it’s outer ____ is completely filled with?
Its outer shell is filled with electrons.
What electorns configuration represents the most chemically stable atom?
The electron configuration that represents the most chemically stable atom is the noble gas configuration, which is when an atom has a completely filled valence shell. This configuration is stable because it has a full complement of electrons and is unlikely to gain or lose electrons.
What is the most stable atom and why?
The most stable atom is helium because it has a full outer electron shell, which makes it less likely to react with other atoms.
In order to become a chemically stable ion a neutral atom of calcium will?
It would have to lose two electrons.
