Atoms are made up of three fundamental particles called protons, neutrons and electrons. Protons and neutrons are found in the nucleus at the centre of the atom whereas electrons are found in shells orbiting the nucleus. Atoms are neutral and contain the same number of protons as electrons. Protons, neutrons and electrons — are composed of even smaller particles, such as quarks.

Atoms are made up of three particles known as subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don't have a charge.A fundamental rule is that particles with the same charge are repulsed from each other, while particles with opposite charges are attracted to each other.
The nucleus (or center) of an atom is made up of protons and neutrons. The number of protons in the nucleus, known as the "atomic number," primarily determines where that atom fits on the Periodic Table. The number of protons in the nucleus also defines in large part the characteristics of an atom—is it a gas or a metal, for example. Two atoms with an identical number of protons in their nuclei belong to the same element.
Now, while the protons are the same in an element, the number of neutrons may vary from atom to atom. The number of neutrons determines what isotope an atom is.
The nucleus of an atom is surrounded by a cloud of electrons. Remember, electrons are negatively-charged and are attracted to the positively-charged protons in the nucleus. An atom is considered to be electrically neutral if it has an equal number of protons and electrons.
An important principle to know is electrons may be transferred from one atom to another or even shared between atoms (allowing atoms to bind together). These bonds allow for the formation of molecules, combinations of atoms (including those of different elements).
