Answer:
An atom is the smallest particle in a chemical element that holds its chemical properties. Although in the past it was thought impossible to break an atom, within modern chemistry we know that an atom is composed of subatomic particles, which compose the atomic model:
1) electrons, which have a negative charge, such a small size that it is immeasurable, and a mass much smaller than the other two subatomic particles; 2) protons, which have a positive charge; and 3) neutrons, which have no charge.
The protons and neutrons form a dense and massive atomic nucleus, which is called multipons nuclei. The electrons form a cloud of electrons that surround the nucleus.
extinct organisms; that is, they belong to species that are no longer living anywhere on Earth. (3) The kinds of fossils found in rocks of different ages differ because life on Earth has changed through time.
