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).
Part A The atom consists of three types of subatomic particles: protons, neutrons, and electrons. The electron is by far the lightest of the three, while the much heavier proton and neutron have masses very similar to each other. Two of the types of particles carry an electrical charge, while the third is neutral.
