Element

The video tutorial introduces elements as substances that cannot be broken down chemically, each with a unique symbol. It explains the atomic structure of elements, highlighting protons, neutrons, and electrons. The tutorial uses water as an example to illustrate the composition of molecules from elements. It also touches on the mysteries within atoms and ends with a reflective question about the difference between atoms and elements.

How do the numbers of protons, neutrons, and electrons distinguish one element from another?
