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).
We'll start with the subatomic particles, electrons, protons, and neutrons, and then look at the mass of an atom (the mass number), how the particles are arranged in an atom (its structure), and what determines an element's identity (the atomic number).lectrons. All atoms (except hydrogen)* consist of 3 kinds of particles: protons, neutrons, and electrons. The properties of an atom â its mass, its charge, what element it is, what isotope of that element it is â are completely determined by how many of each kind of particle it has.
