ChemVocab

=**Chemistry Vocabulary**= Molecule- A molecule is the smallest particle of a substance ** Neutron- a subatomic particle of about the same mass as a proton but without an electric charge. Electron - a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids. ** Mixture- a substance made by mixing other substances Periodic Table- a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns. ** Nonmetal- an element or substance that is not a metal. Metalloid- an element (e.g., arsenic, antimony, or tin) whose properties are intermediate between those of metals and solid nonmetals or semiconductors. Property- a characteristic of a substance that describes its ability to change into other subtances ** Ductility- of a metal) able to be drawn out into a thin wire. Malleability- of a metal or other material) able to be hammered or pressed permanently out of shape without breaking or cracking. Electrical Conductivity- the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field Density- the degree of compactness of a substance Magnetism- a phyiscal phenomenon produced by motion of and electric charge resulting in attractive and repulsive forces between and objects. Solubility- (of a substance) able to be dissolved Boiling Point- the temperature at which a liquid boils and turns to vapor. Melting Point- the temperature at which a given solid will melt. States of Matter- the distinct forms that different phases of matter take on Specific Heat- he heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree). Volume- the amount of space that a substance or object occupies, or that is enclosed within a container Mass- Length, height, and Width of space matter takes up. Example- The school takes up 20 acres of Snow Hill. Precipitate- to be deposited in solid form from a solution. Exposure -the state of being exposed to contact with something Potency -power or influence Dose- a quantity of a medicine or drug taken or recommended to be taken at a particular time Concentration- The amount of one material in a certain volume of another material. Individual Susceptibility **
 * Below you will find a list of each of the vocabulary words important to our chemistry unit. You MUST define at least one word and give an example of another word as they pertain to chemistry to receive points for this part. You WILL be responsible for ALL of the words and their definitions.**
 * Matter- physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, esp. as distinct from energy
 * Atom the smallest component of an element having the chemical properties of the element **
 * Proton- a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
 * Compound- two or more groups of elements cobined. Ex: Water(H2O)=Hydrogen+Oxygen.
 * Metal- a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and
 * Reactivity- the state or power of being reactive or the degree to which a thing is reactive.
