Des Dichado is wrong. Obviously, the number cannot be calculated exactly, but it can certainly be approximated. Wikipedia gives the six most abundant elements by mass in humans (constituting 98.7%) as, in order, oxygen (65%), carbon (18.5%), hydrogen (9.5%), nitrogen (3.2%), calcium (1.5%), and phosphorus (1%). Given the mass of a person, it's simple math to calculate the number of moles of each element in the person. Each element has a most abundant isotope, which has a known number of subatomic particles. I calculated that an 80 kg human (~176 lbs) has approximately 7.36*10^28 protons, neutrons, and electrons.

How many subatomic particles are there in the element xenon?
Like all other atoms it contains three subatomic particles, they are Protons, Neutrons and Electrons.
How many subatomic particles are there in iodine?
It would depend on how much iodine is present. The greater the mass the more particles there would be
What are the properties of particles?
The atom is the smallest part of matter that represents a particular element. For quite a while, the atom was thought to be the smallest part of matter that could exist. But in the latter part of the 19th century and early part of the 20th, scientists discovered that atoms are composed of certain subatomic particles and that, no matter what the element, the same subatomic particles make up the atom. The number of the various subatomic particles is the only thing that varies. Scientists now recognize that there are many subatomic particles (this really makes physicists salivate). But in order to be successful in chemistry, you really only need to be concerned with the three major subatomic particles: Protons Neutrons Electrons
How many subatomic particles does calcium have?
Calcium atoms have 20 protons and 20 electrons. The number of neutrons varies with the isotope.
How many subatomic particles are in the element xenon?
The "subatomic" particles in atoms are usually considered to be only protons, neutrons, and electrons, although these may contain sub-subatomic particles such as quarks and gluons. Every atom of xenon contains 54 protons and 54 electrons, because 54 is the atomic number of xenon. Every atom of xenon also contains neutrons. The lightest naturally occurring and radioactively stable isotope of xenon is Xe-124. Since the mass number is the sum of protons and neutrons, the total of protons, electrons, and neutrons for this isotope is 124 + 54 or 178. The number of particles for any other isotope of xenon may be found by adding the mass number to the atomic number.
How many subatomic particles in chlorine?
17
How many subatomic particles are present in an atom except proton neutron electron and what are they?

What subatomic particles are found outside the atomic nucleus?
The particles outside of an atom are called electrons :D
How many subatomic particles are there in the element xenon?
Like all other atoms it contains three subatomic particles, they are Protons, Neutrons and Electrons.
How many subatomic particles have been discovered to date?
more than 400
What are positiely charged subatomic particles?
Of the hundreds of subatomic particles, many have an electric charge. The best-know particle with a positive charge is the proton. Subatomic particles are considered only protons, neutrons, electrons. The other particles form the large group of elementary particles (which includes also p, n and e).
How many subatomic particles are there in iodine?
It would depend on how much iodine is present. The greater the mass the more particles there would be
What are the three subatomic particles ina an atom?
