Question

Predict the predominant type of bonding of CsI
covalent bonding
ionic bonding
metallic bonding

Answer 1

What do you think it should be?

Answer 2

Covalent Bonding takes place between two non-metals. But Cs is a metal so option A can not be correct.

Answer 3

so would it be option C ?

Answer 4

Metallic bonding takes place between positive ions and electrons of the same metal.

Answer 5

Ionic bond takes place between a metal and non-metal. Is Cs a metal? and I a non-metal?
Yes

Answer 6

Getting it?

Answer 7

Yes, thank you

Answer 8

Welcome :)

Answer 9

<3 :)

Answer 10

Answer 11

ok thank you

Answer 12

Just for additional information if you want to do it analytically,

If the electronegativity (EN) difference is between 1.6 and 2.0 and if a metal is involved, then the bond is considered ionic.

EN of Cs is 0.7 and that of I is 2.66, this gives you a difference of 1.96 which is between 1.6 and 2.0 and since Cs is a metal involved the bonding will be Ionic.
