I am assuming that the isotopic formula of the element asks you for that notation where you display both the atomic mass (protons + neutrons) and atomic number (protons).

Something like ¹H₁

Then, let's start from the beginning.

34 moles of electrons in X2 = 17 electrons in one atom.
Similarly, 20 neutrons in one atom.

-------------------

With this in mind, what will be the atomic mass? What will be the atomic number?
