Question

What type of ions are formed by transition elements?

Answer 1

They form `color(darkblue)"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 `color(RED)"(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.
