there are 3 main particles - electron, proton and neutron. however, protons and neutrons both contain what are called quarks. proton has 2 up quarks (charge each 2/3), and 1 down quark (charge -1/3) which gives a total charge of +1. Similarily, a neutron has 2 down quarks and 1 up quark (for 0 charge).

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.
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 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 does chromium have?
Chromium has a total of 24 subatomic particles, consisting of 24 protons and typically 28 neutrons in its most common isotope. Additionally, it has 24 electrons, which are equal to the number of protons in a neutral atom. Therefore, when considering protons, neutrons, and electrons, chromium has a combined total of 72 subatomic particles.
How many subatomic particle would be present in an atom of helium with a mass of 4 amu?
6 subatomic particles. 2 protons and 2 neutrons (that accounts for the mass of 4 amu) as well as 2 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 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 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.
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
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.
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 are positiely charged subatomic particles?

What are properties that vary among subatomic 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
What subatomic particles are found outside the atomic nucleus?
The particles outside of an atom are called electrons :D
2 Where are the different subatomic particles located in the atom?
TWO types of subatomic particles?? Gosh, the basics are the electrons, neutrons, and protons. Then you add muons, gluons, 6 quarks and so on, and you come up with many particles. And that's just for matter. If you consider anti-matter, you have positrons, anti-protons, anti neutrons, etc etc etc.
How many subatomic particles are in a nuclide?
The atom of a chemical element contain protons, neutrons and electrons; the number is specific for each isotope.
