Well, if you look at any periodic table, you should be able to find it... You should get to know it well, and be able to find most elements on there.

Is it not in between yttrium and niobium, below titanium and above hafnium?

If we write the zirconium-95 isotope as $\text{_(40)^(95) "Zr}$, its mass number is $95$. So, if its atomic number must be an integer, what is it?
