Final answer:
Matter is composed of smaller building blocks known as atoms, of which there are 118 different types called elements. These atoms can bond together to form molecules, the chemical building blocks for all structures.
Step-by-step explanation:
Matter is composed of smaller building blocks called atoms. Atoms are the basis of all the structures and organisms in the universe, and every material around us is made from different combinations of these atoms. Astonishingly, there are only 118 different types of atoms, referred to as elements, like hydrogen, oxygen, and carbon. But just as a chef creates a diverse array of dishes with a limited number of ingredients, the diversity of materials in the universe arises from the various ways in which atoms can combine to form molecules.
Each element is made up uniquely of one type of atom, and when atoms bond together, they form molecules. These molecules are the chemical building blocks that make up all the body structures and can range from simple structures like water to complex ones like proteins and sugars found in living organisms.
