An implied contract works differently. This type of contract evolves when no written contract is present, but circumstances may cause one person to become unjustly enriched as a result of their actions or an understanding exists. There are two types of implied contracts: 1  Implied in fact. 2  Implied in law.
The word atom is derived from the Greek word atom which means indivisible. Atoms are composed of three type of particles: protons, neutrons, and electron. Protons and neutrons are responsible for most of the atomic mass e.g in a 150 person 149 lbs, 15 oz are protons and neutrons while only 1 oz. is electrons. The mass of an electron is very small (9.108 X 10-28 grams).
Review: 1  Subatomic particles are particles that are smaller than the atom. 2  Protons, neutrons, and electrons are the three main subatomic particles found in an atom. 3  Protons have a positive (+) charge.  Neutrons have no electrical charge.
