Understanding Atomic Structure and Elements

The video tutorial explains how to identify elements on the periodic table by their atomic number, which is equivalent to the number of protons in an element. It specifically focuses on element 26, which is iron, with the symbol Fe. The tutorial emphasizes that the atomic number is found above the element symbol on the periodic table and serves as a guide to determine the number of protons. The video concludes with a recap of these concepts.

What is the relationship between the number of protons and the atomic number?

• They are unrelated.

• The atomic number is the same as the number of protons.

• The atomic number is double the number of protons.

• The atomic number is half the number of protons.

How is the periodic table organized?

• By the number of protons

• By atomic mass

• Alphabetically by element name

• By the number of neutrons
