Zirconium has 40 electrons, 40 protons, and usually 51 neutrons in its nucleus, making it a stable element with an atomic number of 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.
To determine the number of protons in an atom of zirconium, you would look at its atomic number which is 40. This means that zirconium has 40 protons. To calculate the number of neutrons, you would subtract the atomic number from the atomic mass (rounded to the nearest whole number). Zirconium's atomic mass is around 91, so it would have approximately 51 neutrons. Since atoms are electrically neutral, zirconium would also have 40 electrons to balance the 40 protons.
40Ar has 18 protons, 22 neutrons, and 18 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).
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.
Zirconium has 40 electrons, 40 protons, and usually 51 neutrons in its nucleus, making it a stable element with an atomic number of 40.
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.
For an atom of Zirconium-90 with atomic number 40 and an overall charge of 0, it will have 40 protons and 40 electrons. Since the atomic number specifies the number of protons, and in a neutral atom the number of protons equals the number of electrons. As the charge is 0, the number of protons and electrons must balance each other out. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass, so in this case, zirconium -90 indicates it has 50 neutrons (90 - 40).
