Sentences with phrase «individual atoms»
The phrase "individual atoms" refers to the smallest particles that make up everything around us. These atoms are tiny and cannot be divided further. Sometimes, things are made up of many atoms stuck together, but when we say "individual atoms," we mean each atom by itself. Full definition
