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 followingterms and shows the relationship between SOME of the terms properly:

matter:mass and volume density states

energypure substances:

elements compounds

mixtures: heterogeneoushomogeneoussolution [describe types]colloidsuspensiontyndall 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.

qualitativequantitativelustremalleableductileconductivity - thermal and electricalbrittlehardnesssolubledo 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 yourevidence to support your classification.

metals, metalloids [semi-metals], non-metals, compoundsdemonstrate [show me] substance, what you think it is, and the data [evidence] to substantiate yourclaim.
