How many protons does zirconium have?
AnswerThere are 40 protons in the element "zirconium". There are a number of isotopes of Zr, with the most common having an atomic weight (protons plus neutrons) of 90, with 94 and 92 tied for second place. That leaves 50 neutrons as most common, with 52 or 54 neutrons as alternatives.

What element has 92 protons and 146 neutrons?
The element is Uranium , the symbol is (U). The charge is +1 because:Atomic number(Z): # of protons (92), which also tells you what element it is in the periodic table.Ion charge: # of protons (92) - # of electrons (91) = 1Mass number(A): # of protons (92) + # of neutrons (143) =235
