Question

in what way Cobalt and Nickel are different from each other​

Answer 1

Answer:

Nickel melts and boils at a lower temperature. Cobalt is more brittle at sea level. Both are used with other metals to create alloys.

Nickel salts are green

and cobalt salts are red when they are hydrated; that is,

when they have water present. So a little dilute acid will

make a green solution with nickel and red with cobalt.
