Zirconium has 40 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a zirconium isotope = Mass number - 40
The mass number of zirconium 98 is 98. This number represents the total number of protons and neutrons in the nucleus of an atom of zirconium. Zirconium has 40 protons, so the remaining 58 particles are neutrons.
Atomic number = number of protons = number of electrons. The atomic number for zirconium is 40, so the number of protons is also 40 and the number of electrones is also 40. Number of neutrons = Atomic mass of an isotope - Atimic number

77 protons, 115 neutrons.
Zirconium has 40 protons and typically 51 neutrons in its nucleus, giving it a mass number of around 91. The protons are positively charged particles while the neutrons are neutral, together making up the nucleus of the zirconium atom.
An atom's atomic number gives its number of protons. Zirconium's atomic number is 40. Thus it has 40 protons in each atom, regardless of isotope.
An isotope of zirconium will have protons, neutrons, and electrons. Zirconium typically has 40 protons and varying numbers of neutrons in its isotopes. Electrons surround the nucleus of the atom, balancing the positive charge of the protons.

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.

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.
This is the isotope zirconium-93 (51 n + 2 n =53 n plus 40 p).
As is the case for all elements (other than the main hydrogen isotope), a zirconium atom comprises protons, neutrons and electrons.
Zirconium-90 (90Zr) has the atomic number 40, and it has 40 protons. The question asked about a specific isotope of zirconium, and the 90 in this isotope represents the number of protons plus the number of neutrons in 90Zr. The math is simple, and 90 minus 40 tells us there are 50 neutrons in this atom. As the atom was said to be electrically neutral, so that means the number of electrons will be equal to the number of protons. The atom will, therefore, have 40 electrons.
