The number of neutrons for any given element varies, depending on the isotopes. Search the Wikipedia, or Google, for "Isotopes of Zirconium" for the isotopes of this particular element. The list of isotopes will give you the Atomic Mass (protons + neutrons) for the different isotopes; subtract the atomic number (which is the number of protons) to get the number of neutrons for each isotope.
mercury has 121 nutrons because the periodic table
Not sure about nutrons, but xenon has between 70 and 82 neutrons.

Zirconium has 40 electrons.
18 neutrons.
None. Zirconium is not a chemical compound but a mixture. As a result, anything that contains zirconium in it will be a mixture.
Zirconium has 40 electrons in its neutral state.
Zirconium is a metal element. There are 40 electrons in a single atom.
Zirconium is a metal element. Atomic mass of it is 92.
Typically, 69. However it can vary by isotope.
Zirconium bonds with many atoms including oxygen, nitrogen, sulfur, and the haloegens.
