Snc1d - Classification Of Matter

SNC1D - Introduction to chemistry! Chemistry is the study of matter and the changes matter undergoes. However: Chemistry is all about electrons. To understand this statement we want to define, classify and organize a number of concepts: Your task, in pairs, is to graphically organize the following terms in a way that describes the following terms and shows the relationship between SOME of the terms properly: matter: mass and volume density states energy pure substances: elements compounds mixtures: heterogeneous homogeneous solution [describe types] colloid suspension tyndall effect explain how to tell the difference between a homogeneous and heterogeneous solution. During the lab: A large number of elements and compounds have been left out on the bench. You must do the following. define the following terms and use them to investigate the elements and compounds. qualitative quantitative lustre malleable ductile conductivity - thermal and electrical brittle hardness soluble do not define these, I assume you know: shape, size, colour, we NEVER taste and rarely smell Use the above to attempt to cassify the elements in compounds into four groups: be sure to show your evidence to support your classification. metals, metalloids [semi-metals], non-metals, compounds demonstrate [show me] substance, what you think it is, and the data [evidence] to substantiate your claim.
