A radioactive atom is an atom of an element with an unstable nucleus.
Some characteristics of a atom are they take on part of chemical reactions independently. Atom can be divided into sub-atomic particles and the main particles of a atom are the electron, proton and 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.
That would be an atom. Atoms go down to protons, neutrons and electrons, but these do not have unique characteristics. So, the smallest particle with unique characteristics is an atom.

This particle is the atom.
These are the electrons.
An atom of that element has all the properties of that element.
The smallest particle of any substance that maintains elemental characteristics and identity is an atom. Conversely a pure elemental sample if divided indefinitely into smaller pieces would ultimately yield the atom.
That would be AN ATOM.
The atom.
An atom is the smallest building block of matter that retains the characteristics of that matter.
The smallest particle of an element that still retains the chemical characteristics of that element is called an atom. Each element is made up of atoms, which are composed of protons, neutrons, and electrons.
