Question

Is nickel a cation or an anion?

Answer 1

hey mate Here is ur ans

nickel is a cation
Ni(+2)

explanation

Nickel is a metal
so it has the tendency to lose electrons thus becoming a positively charged ion called cation

It has atomic number 28 thus it has 2 electrons in the valence shell which it can donate
thus acquiring a +2 charge

However it can also show charge of +1 and +3 but +2 is the most common oxidation state (loss of electrons is oxidation)

hope it helps you frnd

Answer 2

Nickel is a cation.

The formulae of nickel would be Ni+
for nickel 2 it would be Ni+2
And
For Nickel3 it would be Ni+3
