what is the difference between an atom and a element? and a molecule and compund?
well a compound is a combo of two molecules or elements an atom is a basic unit of an element
if you imagine that atoms are brick, and elements are types of bricks, it should explian itself. atoms are the smalledt parts of matter, and elements are types of atoms a molecule is a combination of 2 or more atoms, while a compound is a combination of 2 or more elements
this website has the answer, and welcome to open study! c:
Thats a good link @lowcard2! Slightly inaccurate @annikaroo: you are right you need two or more atoms to make a molecule, but generally crystalline, ionic compounds are not included in this category. Like the first statement in the link describes: "A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds."
