Matter is anything that takes up space, by having a volume, and has mass. Matter can exist in a solid, liquid, gaseous (vapor), or plasma state. All matter is made up of certain basic substances called elements. Elements can be further classified as being either essential or trace elements. Essential elements are required for human life Trace elements are required only in small quantities. Elements cannot be broken down to simpler substances and there are only ninet...
