There are 40 protons in 90Zr. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons.
Zirconium's atomic number is 40. Therefore, it has 40 protons. Its most abundant stable isotope is 90Zr, meaning it has 90 - 40 = 50 neutrons.
THERE IS 40 protons in zirconium.
Zirconium has 40 electrons and protons.
40 protons
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
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
The isotope of zirconim, 91Zr, has 51 neutrons. In order to solve this problem, one must know that an element's atomic weight is the average of its number of protons and neutrons (only neutrons are variable). Since the atomic number is the number of protons, the atomic number subtracted from the atomic weight gives the number of neutrons. An element in period 5 that has this many neutrons is found to be zirconium (the isotope 91Zr).

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
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.
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).
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
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.
As is the case for all elements (other than the main hydrogen isotope), a zirconium atom comprises protons, neutrons and electrons.
All the isotopes of chemical elements contain protons, neutrons and electrons.
The isotope of zirconim, 91Zr, has 51 neutrons. In order to solve this problem, one must know that an element's atomic weight is the average of its number of protons and neutrons (only neutrons are variable). Since the atomic number is the number of protons, the atomic number subtracted from the atomic weight gives the number of neutrons. An element in period 5 that has this many neutrons is found to be zirconium (the isotope 91Zr).
