Exploring the Building Blocks of Matter: Comparing Different Types of Atoms

The video tutorial explains that not all atoms are the same due to differences in protons, neutrons, and electrons. It introduces over 100 different elements, focusing on helium and aluminum. Helium is a gas used in balloons, while aluminum is a metal used in various products. The atomic structure of aluminum includes 13 protons, 14 neutrons, and 13 electrons, giving it an atomic number of 13. Helium has 2 protons, 2 neutrons, and 2 electrons, with an atomic number of 2. The video highlights the differences in atomic structures between these elements.
