Atoms Molecules And Compounds Explained

The video tutorial explains the differences between atoms, molecules, and compounds. It begins by describing atoms as the smallest unit of matter, composed of subatomic particles like protons, neutrons, and electrons. The tutorial then explains how molecules are formed by connecting atoms through covalent bonds, using examples like ozone and water. It further distinguishes compounds as chemical combinations of different elements, exemplified by sugar. The video concludes with a reminder about the importance of kindness.
