Charge. Protons are positive, neutrons are neutral.
protons and neutrons in its nucleus. The number of protons determines the element, while the number of neutrons can vary to create different isotopes of that element.
One model of the atom has "subatomic particles": electrons, protons, neutrons. The protons and neutrons, according to this model, are made up of three different kinds of quarks each.
A hydrogen atom typically has one proton and one electron, with no neutrons in its most common isotope. An oxygen atom has eight protons, eight electrons, and usually eight neutrons, though there are isotopes of oxygen that may have different numbers of neutrons.
Up quarks and down quarks are in protons and neutrons.
Well your question is not exactly clear. But the ONLY thing that defines one element from another is the number of protons it has. Hydrogen has 1 proton, helium has 2 protons and so on. A neutral atom has an equal amount of protons and neutrons. An isotope is an atom that has an imbalace of of protons and neutrons, but only the number of neutrons can change. Never protons, because that would make it another element. Protons and neutrons each wiegh 1amu (atomic mass unit). A neutral helium atom has 2 protons and 2 neutrons. So its atomic weight is pretty much 4amu. Electrons wiegh 1836 times less than 1amu so they are almost signifigant to the mass of an atom. Number of protons make an element what it is.

protons (3) THEN neutrons (4) THEN electrons (3) :D
Two atoms with the same number of protons are not two elements but one element. If they have differing numbers of neutrons, however, they are said to be of different isotopes.
An isotone is a group of atomic nuclei that have the same neutron number but different atomic numbers. This means isotones have the same number of neutrons but different numbers of protons. Isotones are different from isotopes, which have the same atomic number but different numbers of neutrons.
protons are positive
An isotope of an element has the same number of protons but a different number of neutrons. One of the most common is deuterium (heavy water), an isotope of hydrogen that has one neutron instead of the usual zero.
No, it is just the other way around!All isotopes of one particular element have the same number of protons (specific for that element) but are differing in neutron number.Example:Uranium has 92 protons (same as atomic number),butisotope U(235) has 143 neutrons and 92 protons (143+92=235)andisotope U(238) has 146 neutrons and 92 protons (146+92=238).
The atomic structure of isotopes of boron is the same in terms of the number of protons in the nucleus (5), but different in the number of neutrons. This difference in neutrons gives each isotope a different atomic mass.
An element must always have the same number of protons as it's atomic number. The number of electrons may vary, making an atom into an ion, and the number of neutrons can also vary which is why we have different isotopes of the same element.

The mass number in chemistry represents the total number of protons and neutrons in an atom's nucleus. It is used to identify isotopes of an element, where different isotopes have the same number of protons but a different number of neutrons.
Protons and neutrons, firstly, are much larger than electrons. They are packed tightly together in the center of the atom, while electrons flow freely in all directions around them. Also, protons are positively charged, electrons are negatively charged, and neutrons have no charge at all.
