Charge. Protons are positive, neutrons are neutral.
Isotopes are atoms that have the same number of protons, but different number of neutrons in the nucleus of the atom. So the Carbon atom normally has 12 protons and 12 neutrons, but a few carbon atoms have 12 protons and 14 neutrons. The number of protons in the nucleus and electrons in the shell determine the properties of the element, but the extra neutrons can cause the element to be a little heavier or lighter than normal.
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.
Up quarks and down quarks are in protons and neutrons.
The number of electrons and neutrons may differ for atoms of the same element. However, what distinguishes atoms of one element from those of a different element is the number of protons in the atom's nucleus. All of the atoms of an element have the same number of protons, which is the single most important determiner of the properties of an element.
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.
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).
Isotopes are atoms of the same element with different numbers of neutrons, but the same number of protons.

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.
protons (3) THEN neutrons (4) THEN electrons (3) :D
protons are positive
As the atomic number rises one, one proton, one electron, and a variable amount of neutrons are added.
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.
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 protons and the neutrons are located in the nucleus of an atom.
Hydrochloric acid consists of one Hydrogen and one Chlorine atom - HCL. Hydrogen has only one proton, Chlorine has 17 Protons, 18 neutrons so HCL has 1 + 17 = 18 protons, 0 + 18 neutrons = 18 neutrons, HCL has 18 protons and 18 neutrons.
All atoms of the same element have the same number of Protons and Electrons in their atoms and also have a varying of number of Neutrons.Atoms of different elements have different numbers of Protons, Electrons and Neutrons.------------------------------------------------------------------It all depends on the substance the atoms are in. One thing for certain is there is the same amount of protons as there is electrons, unless the atom is ionized (has a net electrical charge). An anion (negatively charged atom) has more electrons than protons; a cation (positively charged atom) has more protons than electrons.the little number is the number of protons, the bigger number is the number of protons and neutrons added together.soprotons=electronsbig number-protons= neutronsget it?
