Fossils are the preserved remains or traces of animals, plants, and other organisms from the past.
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
Usually only a portion of an organism is preserved as a fossil, such as body fossils (bones and exoskeletons ), trace fossils (feces and footprints), and chemofossils (biochemical signals).
Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.

1. A metal is a solid substance, usually hard. On the other hand, a non-metals is a solid or gaseous material, in which the metallic properties are absent.
2. When a new substance is formed at that time we can understand that chemical reaction has taken place. It can't be reversed.
4. Neutron = no charge
Electron = negative
Proton= positive
5. Nucleus has a positive charge.
6. An atom is bigger. Because electrons are what takes up space in atoms, the result is that the size of the biggest filled orbital determines the size of the atom or ion.
