What occurs when potassium reacts with chlorine to form potassium chloride

The bond between K⁺ and Cl⁻ ions is an ionic bond

Atoms have different stability. Unstable atomic atoms will try to form stable electron configurations like those of noble gases. Where noble gases have the number of outer electrons 2 or 8

The formation of electron configurations such as noble gases can be done by forming shared ions or electron pairs

Atoms with high ionization energy and atoms that are difficult to draw electrons will form bonds with shared electron pairs (electrons can be from one atom or two atoms attached)

Inform ions, atoms will release or attract electrons

Ion bonds occur because atoms that have low ionization energy (easily release electrons) form a + ion, and these electrons are bound by atoms that have large affinity energy (easily pulling electrons)

Generally, ionic bonds occur in metals and nonmetallic elements. Metal elements have low ionization energy and non-metallic elements have a high electron affinity

In Atoms, to achieve stability, K will release one electron so that it has an electron configuration like noble gas Ar

Electron configuration of K (atomic number 19) and Ar (atomic number 18)

K: 2 8 8 1

Ar: 2 8 8

so that it becomes a K⁺ ion

While the Cl atom will bind one electron, so it has an electron configuration like noble gas Ar

Cl: 2 8 7

Ar: 2 8 8

So that it becomes a Cl⁻ ion

Finally, there will be an attractive attraction between positive and negative ions and KCl is formed

So the bond between K + and Action is an ionic bond

a sequence is a function whose domain is the set of natural numbers.

natural numbers are all the negative and positive integers

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
