Question

Sodium chloride (table salt,) whose formula is NaCl:
Ionic
Covalent

Answer 1

Since sodium chloride contains both a metal AND a nonmetal, the combination of those would result in an ionic bond.

Answer 2

Answer: Ionic

Step-by-step explanation:

Ionic bonds are formed by transfer of electrons between metal and non metals. Covalent bonds are formed by sharing of electrons between non metals

In Sodium chloride

Electronic configuration of sodium:

`[Na]=1s^22s^22p^63s^1`

Sodium atom will loose one electron to gain noble gas configuration and form sodium cation with +1 charge.

`[Na^+]=1s^22s^22p^63s^0`

Electronic configuration of chlorine:

`[Cl]=1s^22s^22p^63s^23p^5`

Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.

`[Cl^-]=1s^22s^22p^63s^23p^6`

In sodium chloride the one electron from sodium metal gets transferred to chlorine atom and thus is ionic.
