Presentation transcript:

Chapter 2 Section 3 -Substances can be classified as either elements or compounds element- the simplest form of matter that can exist under normal conditions -cannot be separated into simpler substances *look at periodic table

-Two or more elements can combine chemically with one another to form a: compound- substance that can be separated into two or more substances only by chemical means *CO 2, H 2 0 -look at page 36 figure 2.6 -Sample Problem 2-2, #13 page 39

-There are over 100 known elements chemical symbol- one or two letter representation of an element -first letter is always capitalized -second letter, if used, is lower case -many are derived from Latin or Greek names for the elements
