Question on: JAMB Chemistry - 2024
Na2X ⇌ 2Na+ + X2-
The bond between Na and X is likely to be:
A
covalent
B
dative
C
ionic
D
metallic
Ask EduPadi AI for a detailed answer
Correct Option: C
The dissociation of Na2X into Na+ and X2- indicates the formation of ions. Therefore, the bond is:
- Ionic bonds: Formed by transfer of electrons and electrostatic attraction between ions.
- Covalent bonds: Involve sharing of electrons.
- Dative bonds: A type of covalent bond where both electrons come from the same atom.
- Metallic bonds: Characteristic of metals with delocalized electrons.
Since ions are formed, the bond between Na and X is most likely ionic.
