Isotopes

Welcome to our lesson on isotopes! In this video, we’ll explore the fascinating concept of isotopes and how they enhance our understanding of atomic structures. You will learn about the differences between isotopes of the same element, focusing on how they have the same number of protons but different numbers of neutrons.
📚 In this lesson, you will learn:
How to define isotopes and recognise their unique characteristics.
The significance of mass number and atomic number in identifying isotopes.
How to identify isotopes by their element name and mass number, such as carbon-12, carbon-13, and carbon-14.
How isotopes maintain the same chemical properties despite differences in mass number.
✨ Key concepts covered:
Identifying isotopes: Learn how to determine isotopes from their mass numbers and understand why isotopes have the same atomic number but different mass numbers.
Atomic structure variation: Understand the role of neutrons in creating isotopic diversity within the same element.
Chemical properties of isotopes: Discover why isotopes have identical chemical behaviours due to their electron configuration.
Unstable isotopes and radioactive decay: Get an introductory insight into why some isotopes are unstable and how this affects their abundance.
🤔 Common Questions Answered:
