Sentences with phrase «reactive molecules»
"Reactive molecules" refers to chemicals or particles that are easily influenced by their surroundings and can quickly undergo chemical reactions with other substances. These molecules are often highly unstable and have the ability to either accept or donate electrons, making them capable of participating in chemical reactions. Full definition
