Understanding Atomic Numbers and Elements

The video tutorial explains how to determine the number of protons in an element using the atomic number from the periodic table. It specifically identifies Boron as the element with five protons, corresponding to atomic number five. The tutorial emphasizes that the atomic number is typically found above the element symbol and is a whole number. The video concludes with a recap of these concepts.

What does the atomic number of an element represent?

• The atomic mass

• The number of electrons

• The number of protons

• The number of neutrons

How can you determine the number of protons in an element using the periodic table?

• By looking at the atomic mass

• By counting the number of electron shells

• By checking the atomic number

• By identifying the element's color

Which element has an atomic number of 5?

• Carbon

• Boron

• Oxygen

• Nitrogen

Where is the atomic number typically located on the periodic table?

• To the left of the element symbol

• Above the element symbol

• To the right of the element symbol

• Below the element symbol

What is the significance of the atomic number being a whole number?

• It shows the number of protons

• It represents the average atomic mass

• It is used to calculate the element's density

• It indicates the number of neutrons
