What are the parts to an atom?

Answer 1

An atom is made up of a central nucleus (in which are to be found neutrally charged neutrons and positively charged positrons) which bears a positive charge. Surrounding this nucleus are shells in which may be found electrons (which are negatively charged). The number of electrons matches the number of positrons and the number of positrons determines the element to which the atom belongs.

Answer 2

Mainly, there are 2 parts, the outer circle is made of electrons, and the inner circle is made of protons and neutrons. Protons have a positive charge, neutrons have no charge at all (they are neither negative nor positive), and electrons have a negative charge, so they cancel out the effects of the protons. I hope this helps you, and to my knowledge, this is accurate.

Answer 3

The name "Atom" means "indivisible" in Greek. However, today we know that atoms are composed of electrons, neutrons and protons.

Those three particles can be divided even further. There are dozens of particles and we are still finding new ones. For a pretty good list, check out the link made below.

------------------------------------------------------------------------

Simply put, the building blocks of atoms are electrons, protons and neutrons. The later two live in the nucleus of the atom while electrons form a cloud that orbits the atom's nucleus.

However, if you start to look at protons and neutrons, then a proton is composed of 3 'even more' fundamental particles comprising two up quarks and one down quark, while a neutron is made of two down quarks and one up quark.

If you then smash atoms into one another at close to the speed of light and with great energies as they do in the Large Hadron Collider (LHC), then a whole range of new particles can be made from the energy of the collision (E=MC2 or M=E/C2) and the 'contents' of the colliding atoms.
