Best Answer

The wide variance in their electronegativity. Chlorine has such a powerful electronegativity compared to sodium that it " takes " the sodium's electron into it's valance shell. Thus.

Na +

and

Cl -

attract each other and form

NaCl

sodium chloride.

All atoms want to have a perfect outer layer of 8 electrons. Sodium's electron configuration is 2-8-1, where each number represents a layer of electrons, with the last number being the outer layer. Chlorine has an electron configuration of 2-8-7. If sodium were to lose and electron and give it to chlorine, both of these atoms would then have the perfect outer layer of 8. That's what happens when the two form an ionic bond.

Sodium and Chlorine form an ionic bond. The Sodium(Na+) is the cation which gives one electron to the anion Chlorine(Cl-) which accepts the electron. This ionic bond is weak however, and it's usually soluble in water.

When sodium atoms (Na) and chlorine atoms (Cl) join to make sodium chloride or table salt they form an ionic bond. Using this information which pair of elements is most likely to form an ionic bond?

Ionic bond exist between metals and nonmetals.


What type of bond between sodium and chlorine?

An ionic bond as there is an actual transfer of electrons between the two elements in the product, Sodium Chloride. Sodium gives away one electron in order to become stable, i.e., get noble gas configuration and chlorine accepts that electron (given away by Sodium) to become stable. Thus, an ionic bond is formed between them.


Is sodium chlorine a ionic or covalent bond?

Ionic


What type of chemical bond holds the sodium and chlorine atoms together in table salt?

Ionic bonding


The ionic bond of sodium chloride is formed when?

The ionic bond of sodium chloride is formed when chlorine gains an electron from sodium.


Type of bond formed between Na and Cl?

Sodium chloride (NaCl) does not react with chlorine. The bond between sodium and chlorine atoms to form sodium chloride is ionic. The sodium ion loses one electron to the chlorine atom, forming a Na+ ion and a Cl- ion. The electrostatic attraction between the two oppositely charged ions forms the ionic bond.


Is NaCl a ionic or covalent bond?

Ionic, chlorine does not share any electrons with sodium to form a bond.


Why is sodium chloride a ionic bond?

Sodium chloride has an ionic bond because a big electrostatic attraction between ions of sodium and chlorine exist.
