The only isotope video you need to watch

This video tutorial explains isotopes, which are variations of the same element with different masses due to differing numbers of neutrons. It covers the basic concepts of atomic structure, including protons, neutrons, and electrons, and how these relate to isotopes. The video provides examples using sodium and carbon isotopes, illustrating how the number of neutrons changes while the number of protons remains constant, resulting in different mass numbers. The tutorial emphasizes the importance of understanding atomic notation and encourages viewers to review related topics for a comprehensive understanding.

What is an isotope?

• An element with a different number of electrons

• A variation of the same element with different masses

• A molecule with the same number of atoms

• A different element with the same mass

How do isotopes of the same element differ?

• By having different numbers of neutrons

• By having different atomic numbers

• By having different numbers of protons

• By having different numbers of electrons

In the example of sodium isotopes, what is the difference between Sodium-22 and Sodium-23?

• Sodium-22 has more electrons than Sodium-23

• Sodium-23 has a different atomic number than Sodium-22

• Sodium-22 has more protons than Sodium-23

• Sodium-23 has more neutrons than Sodium-22

What is the mass number of Carbon-13?

• 12

• 6

• 14

• 13

Why do Carbon-12 and Carbon-13 have the same number of protons?

• Because they are isotopes of the same element

• Because they have the same mass number

• Because they are different elements

• Because they have different atomic numbers
