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).
The three main atomic particles are protons, neutrons and electrons. The atomic number of an atom identifies the number of protons in the atom. This is the defining characteristic of an element. An atom can gain or lose neutrons or electrons while retaining its elemental identity. If the number of protons in an atom changes, however, the atom becomes a different element.
