Choose the predominant type of bonding as ionic, covalent, or metallic for the substance below. NiSn
podryga [215]

Answer:

Metallic.

Explanation:

Hello,

In this case, when nickel and tin bond, the difference in their electronegativities results:

\Delta E=E_{Sn}-E_{Ni}=1.96-1.91=0.05

Such difference, in addition to the fact that nickel is a transition metal and tin a metal, will suggest that the predominant type of bond for this substance is metallic as the attractive force between the conduction of electrons and positively charged metal ions is present.

Best regards.

A carbon atom and a hydrogen atom form what type of bond in a molecule? see concept 2.3 (page 36)
svetoff [14.1K]
A bond is a force of attraction between atoms. They are mainly fthree types of bonds namely; ionic bond, which involves transfer of electrons between a metal and a non metal, covalent bond which occurs between non metal atoms by sharing of electrons, metallic bond which is a bond in the metal structure between metal atoms and the sea of electrons. in this case carbon and hydrogen are non metals hence they will have a covalent bond between their atoms.
