Understanding Atomic Number and Elements

The video tutorial explains how to identify elements based on their number of protons using the periodic table. It highlights that the atomic number, which equals the number of protons, is key to identifying elements. Specifically, it shows that carbon has an atomic number of six, meaning it has six protons. The tutorial emphasizes the importance of atomic numbers in distinguishing different elements.

Which element is identified by having six protons?

• Oxygen

• Nitrogen

• Carbon

• Helium

What does the atomic number on the periodic table represent?

• The atomic mass

• The number of protons

• The number of neutrons

• The number of electrons

Where is the atomic number located on the periodic table?

• At the bottom of the element symbol

• At the top of the element symbol

• Below the atomic mass

• Next to the element name

What is another name for the atomic number?

• Proton number

• Neutron number

• Mass number

• Electron number

Why is carbon identified as the element with six protons?

• Because its atomic mass is six

• Because it is the sixth element in the periodic table

• Because it has six electrons

• Because its atomic number is six
