Remember me? I am Joe. I am here to help you learn about elements. So lets get started.
2
Anything that has mass and volume. Mass is the amount of matter in an object. Volume is the amount of space an object occupies.
3
Matter can exists in 4 forms, but only 3 are found on Earth. Solid Liquid Gas Plasma (only found in stars)
4
The building blocks of matter. Not that kind of building block Joe! I love leggos! The smallest piece of matter with all the properties of that matter.
5
Consists of only one type of atom. Cannot be broken down into a simpler type of matter. Can be a single atom or more than one of the same kind of atom. Elements are pure substances they are not mixed with any other one of the elements.
6
Chemical symbols are like initials or abbreviations. They tell us what element we are working with. Here are some examples. Remember that Calcium - Ca chemical symbolsPotassium - K use one capitalIron - Fe letter which canSodium - Na be followed by Aluminum - Al one or twoMagnesium - Mg lower case letters.Silicon - Si
7
Compounds occur when two or more different elements join together to make a new substance that has different properties from that of the original elements. Like salt NaCl.
8
Remember compounds must have two or more different elements in them so there will be two or more capital letters. Water - H 2 O Sugar - C 6 H 12 O 6 Salt - NaCl Rust - FeO
