Answer:
ionic
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
There are one valance electron in sodium so it needed to lose one valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus electrons lost by sodium atom is gained by atom of chlorine and form ionic compound.
2Na + Cl₂ → 2NaCl
