Neon
No, the chlorine atoms do not return the electrons to the sodium atoms.
In its non-ionized state, which is usually how it is found since it's an inert gas, argon has 18 electrons.All atoms have the same number of electrons and protons. According to the periodic table, argon has 18 protons. It therefore also has 18 electrons.Number of Protons/Electrons: 18
Gas. Extremely unreactive. EXPLANATION: It is a noble gas (inert). This means it has a full shell of outer electrons. Atoms spend their lives trying to get a full shell of outer electrons because it will make them really stable, and they do this by reacting with other atoms. Argon has a full outser shell of electrons therefore it is stable and unreactive.
Argon is chemically inert. It does not have free electrons and is not a conductor.
Valence Electrons!
The number of valence electrons in an atom determines if it is inert or reactive. Inert atoms have a full outer electron shell and are stable, while reactive atoms have incomplete outer electron shells and tend to react with other atoms to achieve a stable electron configuration.
Inert gas atoms have a full outer electron shell, making them stable and less likely to gain or lose electrons to form ionic bonds. Additionally, their full outer shell makes it energetically unfavorable for them to share electrons in covalent bonds. Thus, inert gas atoms typically do not participate in chemical bonding.
Inert gases have fully filled outermost shell that is two electrons are present in helium in the outermost orbit and in case of all other inert gases its 8 electrons,therefore inert gases almost never participate in sharing of electrons for forming bonds ie.covalent bond formation
No, eight valence electrons completely fills the valence band and makes the atom inert. The most reactive atoms have either one valence electron or seven valence electrons.
No, sulfur has only 6 valence electrons. Atoms with 8 valence electrons are most stable and generally chemically inert.
An atom is considered inert when it has a full outer electron shell. For most atoms, this means having 8 electrons in the outer shell, except for hydrogen and helium which only need 2 electrons in their outer shell to be stable.
helium has completely filled valence electrons. hence it are stable, chemically inert and do not form compounds.
Atom loose or gain electron to make its octet complete. It is done to achieve inert state.
To figure out what would happen to the electrons when two atoms are placed together, details to electronic configuration of both the participating atoms will be required. For example if interacting atoms are of inert gas then no electrons will be shared or transferred. Refer to the periodic table of elements to get the idea about the electronic configuration of different elements.
Noble gasses have eight electrons in their outher shell(exept Helium, Helium has two.), so the outher shell is fully saturated and have thus no electrical charche so they can't react with each other(there are some exeptions like Fluor, this is because F has the highest electronegativety of all elements.
The noble gases in group 18 are inert.
"Chemically unstable" is ... kind of an odd phrase. Nearly all atoms are "chemically unstable" in the sense that they will react with other atoms (the exception is the noble gases, which react, if at all, only under extreme conditions). Basically, whether an atom will react or not depends on its outer (valence) electrons. A full set of valence electrons (2 for the first shell, 8 for every shell after that) is particularly stable, so atoms will tend to react in such a way as to form them. Alkali metals will try to lose one electron, halogens will try to gain one electron, and so on. The noble gases already HAVE a full valence shell, so they're quite unreactive.
