Understanding Atomic Structure and Elements

This video tutorial covers the importance of protons and atomic numbers in understanding elements. It explains the structure of atoms, focusing on subatomic particles like protons, neutrons, and electrons. The tutorial highlights how the number of protons determines an element's identity and how to use the periodic table to find atomic numbers. It also provides tips for the TEAS exam, emphasizing that memorizing the entire periodic table is unnecessary. The video concludes with practice questions to reinforce learning.
