Sodium (Na) has 1 electron in the 3s orbital and chlorine (Cl) has 7 electrons in the 3p orbital. Sodium gives away the one electron to Cl, leaving it with 8 electrons (octet) in the 2p orbital (like Neon). The chlorine takes that one electron giving it 8 electrons (octet) in the 3p orbital. The sodium then has a +1 charge, and the chloride ion now has a -1 charge. This is an ionic bond.

Formation of NaCl from chlorine and sodium is a chemical process.


The octet rule is the tendency to have electrons in the shell after ion formation or bond formation?

Yes, the octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell with eight electrons, which is considered stable. This stability is achieved by achieving the electron configuration of a noble gas.

Does PCl2F3 follow the octet rule?

yes PCl3 obey octet rule there are 5 electrons in the valence shell of phosphorous it need 3 electron to complete its octet so it form bond with 3 chlorine after bond formation there are 8 electron in its octet it obey octet rule

In naCL why would CL gain the electron?

Chlorine (Cl) would gain an electron in sodium chloride (NaCl) to achieve a full outer electron shell and attain a stable octet configuration, following the octet rule. By gaining an electron, chlorine becomes a chloride ion with a full outer shell, creating an ionic bond with the sodium cation to form a stable compound.


What is octate state?

The octet state refers to a configuration in which an atom has eight electrons in its outermost shell, achieving a stable electron arrangement similar to that of noble gases. This concept is central to the octet rule in chemistry, which states that atoms tend to bond in ways that allow them to have eight valence electrons. Atoms often achieve this stability through the formation of covalent or ionic bonds. The octet state is crucial for understanding chemical reactivity and the formation of molecules.


Is NACL ionic or covalent bonds why cant it be covalent bond?

NaCl is formed by ionic bonds because sodium (Na) donates an electron to chlorine (Cl), resulting in the formation of Na+ and Cl- ions that are attracted to each other by electrostatic forces. Covalent bonds involve the sharing of electrons between atoms, which does not occur in the formation of NaCl.


What do you mean by octet and duplet?

In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.


What is the heat of formation of NaCl?
