Sodium atom

Sodium has an atomic number of 11. Which atom would form an ionic bond with a sodium atom?

Select one:

a. Helium atom

b. chloride atom

c. Carbon atom

d. oxygen atom

I think the answer would be c

Option b) Chloride atom. Because sodium is electropositive and chloride is electronegative. Chloride tends to accept electrons easily and Sodium tends to donate his electron (+1) easily. That makes the the perfect ionic partner.
