Research and Branches of Chemistry
The study of the composition, structure, and properties of matter and the changes it goes through.
Chemistry
The smallest unit of an element that maintains the properties of the element.
Atom
True or False. Properties of matter can be used to classify an unknown substance as a member of a certain group or subgroup.
What is... True?
