Question

If all physical things are made of atoms then why do different physical things have different physical properties?? Like why sodium is soft and diamond is hard

Answer 1

Answer:

Ultimately, the answer boils down to the fact that different elements have different properties because they have different numbers of electrons. Having different numbers of electrons dictates what kinds of compounds atoms of an element will form, and consequently the physical properties (shape, color, texture, smell, etc.) of the compounds.
