Understanding Atomic Number and Cobalt's Unique Properties

This lesson delves into the concept of atomic number, defined as the number of protons in an atom, which gives each element its unique identity. We will also discuss mass number and isotopes, enhancing our understanding of atomic structure. Additionally, we'll focus on cobalt (Co), element number 27, known for its hardness and use in steel alloys, drills, and machine bits. Cobalt compounds, often blue in color, have applications in glass tinting. The radioactive isotope 60Co, found in nuclear fallout, will also be explored.
