Atoms are the fundamental constituents of all elements found in the periodic table. Each element consists of a unique type of atom, characterized by its atomic number. For example, hydrogen atoms form the element hydrogen (H), oxygen atoms make up oxygen (O), and so on. Elements can exist...
Atoms and molecules are the basic building blocks of all “normal” matter in the universe. They make up everything from the simple chemical bonds of water to complex structures like humans. Atoms and molecules have different charges and configurations which create different structures with different...
