If we can't see atoms, how do we know they're there? That's a very good question! Science is all about evidence, so what evidence do we have that atoms really exist? It comes in a variety of different forms: Chemists have long known that when we combine different elements in chemica...
Atoms cannot be created or destroyed. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms. Atoms of same element can combine in more than one ratio to form two or more compounds. How do atoms behave? Electrons are attracted...
