Atomic Structure and Properties

This video tutorial provides an overview of atomic structure, focusing on the three main components: protons, neutrons, and electrons. It explains the characteristics and roles of each component, including their charges and contributions to atomic mass. The tutorial also covers atomic notation, illustrating how to represent elements and their atomic mass on the periodic table. The video aims to reinforce basic concepts of atomic structure for chemistry students.
