Question

which more electro negative NA or CL why​

Answer 1

Answer:

Sodium is a metal ( electro - positive)

It has 9 electrons in its outer cell so , to attain complete electronic configuration it will lose one electron.

And

Chlorine is a electronegative element.

It has 7 electrons in its outer shell so, to attain complete configuration at will gain one electron

Answer 2

Explanation:

Oxygen is more electronegative than chlorine because of the following reasons : ... Oxygen is placed towards the left side of fluorine so has one electron less than fluorine. Chlorine is below fluorine and has a new shell of valence electrons is added to it.

For example, sodium has an electronegativity of 0.93 and chlorine has an electronegativity of 3.16, so when sodium and chlorine form an ionic bond, in which the chlorine takes an electron away from sodium, forming the sodium cation, Na+, and the chloride anion, Cl-. ... These bonds are nonpolar covalent bonds.
