It depends upon which chemical element the atom is a part of .
Most have electrons and protons with Hydrogen the most basic with one each and Lawrencium with 103 elactrons and 159 protons.

∙ 15y agoNobody knows for sure, it is an active area of research and there exists several different theories that predicts what may or may not be found. The Standard Model is the most popular theory, it describes 12 elementary fermions (6 leptons and 6 quarks, each also has an antiparticle so 24 in total) who all have been confirmed. There are also particles called bosons that allow force to be transfered between the fermions, the Standard Model has a total of 12 particles that transfer force (photon for electromagnetism, 3 gauge bosons for the weak nuclear force and 8 gluons for the strong nuclear force) of which one gauge boson (the neutral higgs particle) hasn't been observed yet. One of the drawback with the Standard Model is that it doesn't describe gravity, so the Standard Model and einsteins theory of relativity isn't compatible.

∙ 8y agoThe figure I heard back when I was a kid was 10^80. Let us confirm that number is reasonable. There are A=6.022x10^23 atoms per mole, or 6x10^23 atoms in a gram of hydrogen. 75% of the material universe is hydrogen, 24% is helium. Most of the rest is lithium. Most (96%) of the universe consists of dark matter, about which we know very little. We will pretend, for the sake of this calculation, that that mass also consists of subatomic particles.
The mass of our sun is just under 2x10^30 kg. That is Ms = 2x10^33 grams. About 75% of that is hydrogen, which consists of two subatomic particles (one proton and one electron). Another 24% of the solar mass is helium, which consists of 2 protons, two neutrons, and two electrons (on average). Although the remaining 1% contains elements with many more subatomic particles, to make the math easier I'm just going to tally it up as helium.
So 0.75 (2x10^33 g) x (6.022x10^23 atoms/gram) = 9x10^56 atoms of hydrogen in our sun. The Atomic Mass of Helium is 4, so .25/4 *Ms A = 7.5x10^55 atoms of helium. Multiplying the hydrogen by 2 and the helium by 6 gives us (approximately) the number of elementary particles in the sun: 2.25x10^57.
The mass of the Milky Way galaxy is about 300 billion solar masses, or 3x10^11 Ms. So our galaxy contains 6.75x10^68 elementary particles. The universe beyond contains roughly one hundred billion galaxies. The average size is a little less than that of our galaxy, but there is also some mass between galaxies. So 1x10^11 times the number of elementary particles in the Milky Way yields: 6.75 x 10^79 elementary particles.
We can round that up to 1x10^80. That should put us in the ball park.

∙ 13y agoThat varies. Larger atoms have more protons, neutrons, and electrons than smaller atoms. It also depends on whether you choose to count a proton or a neutron as one particle, or the three quarks that make it up.

∙ 11y agoThis seems to me a very excellent question. However the answer would vary so wildly from one bomb design to another and from one engineering mod on a given design design to another engineering mod on that design and from one field operational configuration to another field operational configuration, there is no definite answer that can be given.
You might as well ask "How many particles are in a motor vehicle?" But remember motor vehicle includes everything from a moped, through motorcycles and cars, to semi-trucks with triple or quadruple trailers. I hope you see the analogy and the dilemma in trying to answer either question.
The smallest bomb that I know was tested is roughly an 11 inch diameter sphere weighing about 56 pounds, the largest bomb that was tested was a cylinder 80 feet tall and 20 feet in diameter weighing well over 500 tons. Both were US devices.
There is no such thing as a nominal atomic bomb.
Just keep on thinking.

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 parts are in an atom?
either 3 or 6 depending on how you look at it, neutrons protons and electrons make up an atom, so there are 3. However these particles are divisible into quarks that make them up, there are 6 quarks, up, down, top, bottom, strange and charm, these combine in different ways to give the subatomic particles mentioned in the first part.
How can you figure out how many of each subatomic particle is in a atom has?

How many total number of particles present in one atom?
The answer depends on the atom! The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.
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 present in an atom except proton neutron electron and what are they?
The only subatomic particles that exist in an atom are protons, neutrons, and electrons.
What are the three subatomic particles ina an atom?
Protons, Electrons and many times Neutrons

How many protons and neutrons does an atom have and where are each of these subatomic particles located?
Atoms can have anywhere from 1 to somewhere around 260-290 subatomic particles. The protons and neutrons are located in a clump in the center of the atom, surrounded by rapidly revolving electrons

What subatomic particles are found outside the atomic nucleus?
The particles outside of an atom are called electrons :D
Who are the founders of subatomic particles?
For the particles in the atom: Joseph Thomson, Ernest Rutherford, James Chadwick and many other precursors, contributors or collaborators.
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).
The nucleus of a helium atom contains four subatomic particles how many neutrons does the helium atom have?
Helium has two neutrons and two protons in its nucleus.
What has a negetive charge?
There are many particles that contribute to the make up an atom. An electron is the subatomic particle that has a negative charge. The muon and tau particle also are negatively charged.
How many subatomic particles does element calcium has?
All elements have three subatomic particles: Protons: positive forces, centered in the nucleus of the atom with neutrons Neutrons: neutral forces, centered in the nucleus of the atom with protons Electrons: negative forces, centered in different energy levels outside the nucleus of the atom Between all these particles, there is only empty space; nothing.
