An atom is the smallest piece of an element that can be identified as that element.
The atomic number
1. Discuss recent developments in the structure of the atom. What new particles have been identified?
An atom.
Radioactivity is identified with radiation detection instruments.
Atoms are normally identified according to the element of which that atom is an example. And that, in turn, is determined by the number of protons in the atom's nucleus. So, any atom that has just one proton is a hydrogen atom. If it has two protons it is a helium atom. And so forth.
