The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
Nucleus
An iron atom is the smallest iron particle that still has the properties of iron.
This particle is the atom.
An atom is the smallest particle of an element that has the properties of that element. The atom consists of a certain amount of electrons, protons and usually neutrons. The amount of each of these sub-atomic particles is what makes an element. No Sub-Atomic Particles have any characterisitics of an element. It is the collective arrangement of electrons and protons (and usually neutrons) which gives an element its characteristics. An atom is the smallest particle that has elemental characteristics.
An atom is the smallest particle that comprises a chemical element.Source:http://en.wikipedia.org/wiki/Atom
Nucleus
An atom.
Protons have positive charge

The subatomic particle in an atom that has a negative electrical charge is called an electron. It's located outside the nucleus and orbits around it in various energy levels.
The smallest particle of an element is called an atom.
An atom is a particle, the smallest particle that can exist by itself.
Yes, a particle can be a single atom.
The large amount of energy imparted upon it in a particle accelerator.
In the atom the particle without electrical charge is the neutron.
The smallest particle that has characteristics of that element is the atom. The atom is made up of a certain amount of protons, electrons and (neutrons) and those are what give the characteristics of that element to that atom.
No, a particle is not the same as an atom. A particle is a small piece of matter, while an atom is the smallest unit of an element that retains the properties of that element.
