Properties and Classification of Oxygen

The video explores whether oxygen is a metal, non-metal, or metalloid by examining its position on the periodic table. It explains that metals are on the left, non-metals on the right, and metalloids in between. Oxygen is identified as a non-metal, located on the right side of the table. The video also describes oxygen's properties, such as being a gas, invisible, and forming negative ions when bonding. The instructor recommends memorizing the metalloids for better understanding.

What are the three main categories of elements in the periodic table?
