Where are the protons electrons and neutrons located in an atom?
The protons and neutrons are found in the nucleus of every atom. Electrons (negatively charged) are found in a cloud surrounding the nucleus of every atom. Protons (positively charged)and neutrons (uncharged) are found inside the nucleus.
What are the nucleons in an atom?
NucleonsNucleons are subatomic particles, such as protons and neutrons, that exist in the nuclei (plural of nucleus) of atoms. Though a proton or neutron can exist outside the nucleus of an atom (though the neutron is unstable and will decay), either particle is considered a nucleon when we refer to them as the constituent parts of an atomic nucleus.Protons and neutrons reside in the NUCLEUS and are thus NUCLEONS. The probability of an electron being within a nucleus is quite small, so it is not considered a nucleon.
How many protons does paper have?
Paper is a compound (def.A thing that is composed of two or more separate elements; a mixture.) so cannot have protons/neutrons/electrons. The pure elements that make up paper CAN have a certain number of protons/neutrons/electrons. Paper is mostly made up of carbon (atomic number 6, atomic mass of 12.0) so carbon has 6 protons. Again, paper itself cannot have protons/neutrons/electrons, you need to break it down until there are elements.
What is the nucleus of an atom made of?
An atom consists of a heavy small nucleus in the center and electrons revolving around it. Nearly all mass is concentrated in the nucleus. The electrons are forming a cloud around the nucleus because they are moving with an enormous speed. Take an example of an atom of Carbon. It has 6 protons and 6 neutrons in the nucleus and 6 electrons revolving around it. Its mass is 12 atomic units and the it has a valency of 4. The nucleus of carbon has a mass of 1.92x10^-26 Kg whereas the six electrons have a total mass of 9.11x10^-31 Kg. We can, in some cases ignore the mass of electros all together. On the other hand the size(radius) of the nucleus of carbon-12 is 2.7x 10^-15m and the size(radius) of an atom of C-12 is 1.7x10^-10m. The density i.e mass per unit volume of C-12 is 2.26x10^3 Kg/m^3 and the density of nucleus of C-12 is 1.7x10^17Kg/m^3. Try calculating it by yourself. It is interesting. Visualize if all the electrons were detached from the nucleus and we have a nuclear mass, how much heavy it will be?
The combined number of protons and neutrons?
Number protons + number neutrons is called the mass number or the atomic mass.
Where does the weight of the nucleus mostly come from?
The nucleus is made up of protons and neutrons. Most of the elements with low atomic numbers are equally protons and neutrons. However, as elements get heavier they will have more neutrons than protons, and since each weigh the same amount (1 atomic mass unit) these nuclei will get most of their weight from the neutrons.
What makes up the weight an atom or molecule?
The number of protons and neutrons controls the weight of an atom.
How many protons are there in an atom of iron?
26 It has 26 protons, 26 electrons and (mostly) 30 neutrons, but 28, 31 and 32 neutrons are natural isotopes of iron as well (though less than 10%).

Three pieces to an atom?
Protons and (mostly) also neutrons (same or more in number), all together in the nucleus.Electrons (same number as protons) orbiting around the centered nucleus in shell's with discrete diameters
What subatomic particles are responsible for the mass of oxygen?
Mass of oxygen or any atom is mostly tied up in the nucleus and largely attributed to neutrons and protons. A smaller amount of mass is contributed by electrons in orbitals outside the nucleus.

A neutral atom always has what?
Atoms are mostly empty space. They do have a nucleus. This contains subatomic particles. Protons. neutrons, and electrons are all subatomic particles. Protons carry a positive charge. Neutrons carry a neutral charge Electrons carry a negative charge. You may want to see the Bhor/plum-pudding model for more information.

What determines the identity of an atom the number of protons the number of neutrons or the number of quarks?
mostly protons, the neutrons will affect it but it would still be the same element, just a different isotope.
Discovered the nucleus and that atom was composed of mostly empty space?
