The Chemistry of Life. Basic Concepts

The Chemistry of Life. The nature of matter Atom: the basic building block of matter. The sub componentic mites that force up atoms ar protons(+) , electrons(-) and neutrons (+/-). The protons and neutrons have more or less the kindred mass. The protons ar positively heydayd instalments (+) and neutrons carry no frisson at all. The electron is a negatively charged particle (-) . They are in constant motion in the coif surrounding the nucleus. Elements and Isotopes. Element: is a pure burden that make up entirely of unrivalled type of atom. Compound: is a substance organise by the chemical substance combination of both or more fractions in definite proportions. Isotopes: atoms of the same element that differ in the number of electrons they contain. Chemical Bonds The atoms in compounds are held unitedly by various types of chemical bonds. The main types of chemical bonds are loft bonds and covalent bonds. An ionic bond is formed when one or mo re electrons are transferred from one atom to other. These positively and negatively charged atoms are know as ions. covalent bond: formed when electrons are shared in the midst of atoms. A molecule is the smallest unit of most compounds. Van der Waals Forces: supple tenderness that develops between oppositely charged regions of nearby molecules.

Properties of pee A water molecule is polar because there is a uneven distribution of electrons between the oxygen and atomic number 1 atoms. weewee is one of the a few(prenominal) compounds found in a unstable state everywhere most of the earths surf ace. desire other molecules, water is neutr! al. The love between a hydrogen atom with a partial positive charge and another atom with a particular negative charge is known as a hydrogen bond. Hydrogen bond is not as plastered as covalent or ionic bond. Cohesion: is an fondness between molecules of the same substance. Adhesion: is an attraction between molecules of incompatible substances. Solutions and suspensions * A mixture is a bodily composed of two or more...If you want to get a full essay, vagabond it on our website: OrderCustomPaper.com
