What type of ions are formed by transition elements?

Answer 1

They form #color(darkblue)"cations"# (positively charged ion).

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.

Transition elements typically form ions with variable charges, known as transition metal ions. These ions can have multiple oxidation states due to the presence of incompletely filled d orbitals in their electron configurations.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
