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).
1 Atom-smallest unit of all matter, that is composed of 3 sub-atomic particles called protons, electrons and neutrons. 2  Proton-the 'heavy' positively-charged particle in the nucleus of an atom. 3  Electron-the very 'light' negatively-charged particle that orbits the nucleus of an atom.lements and Compounds. 1  Element-An element is a substance composed of the same type of atoms (e.g. gold Au, oxygen O 2). 2  Compound-A compound is a substance made of more than one type of atom (e.g. water H 2 O, carbon dioxide CO 2).
