# What type of ions are formed by transition elements?

Jul 3, 2016

They form $\textcolor{\mathrm{da} r k b l u e}{\text{cations}}$ (positively charged ion).

#### Explanation:

As you also have heard them as Transition metals , so the word metal also suggests that they have the tendency of loosing electrons thus gaining a positive (+ve) charge and becoming a cation.

But they have variable charges or oxidation numbers. FOR e.g

IRON has symbol Fe

IT has two types of cations .

Fe^(2+) & Fe^(3+)

And similar is the case with other transition elements $\textcolor{R E D}{\text{(but it doesn't mean every element).}}$

So in the conclusion we can say they form cations and some of the transition elements have variable charges.
