Atoms, Isotopes and Relative Atomic Weights - Theory and Calculations

Learn how to distinguish between different isotopes of an element and understand the concept of relative atomic mass. This lesson covers atomic structure, isotopes, and calculations related to atomic weight.
After this lesson, students will be able to:
Define isotopes as atoms of the same element with different numbers of neutrons.
Calculate the number of neutrons in an isotope given its mass number and atomic number with 100% accuracy in practice problems.
Calculate the relative atomic mass of an element given the isotopic masses and their relative abundances with at least 80% accuracy.

About Me

I am Andrew, but I preferred to be called "Drew". I am from the Philippines, but I have been staying in Indonesia for quite some time and now I am here in England studying Masters of Science in Analytical Chemistry. I am a licensed chemist by profession as well as a licensed teacher back in my home country. I have taught graduate level chemistry as well as IGCSE and AS level chemistry subjects. I guess I would say that, my greatest asset in teaching is my patience to students that are having hard time learning chemistry.

Tutoring Mathematics, Chemistry, Physics (exact subjects).
I am Christian, graduated in chemistry at Utrecht University (Biomolecular Sciences) and have a PhD in developmental biology. For several years now I have been tutoring and exam training in mathematics, chemistry and physics to HAVO and VWO students, but also to HBO students and Cambridge International A-levels. Maybe I can help you too! The lessons are given online, but I provide a personal and interactive approach. With a marker and whiteboard I create an atmosphere that is comparable to private lessons at your home. Every student has unique goals and a unique way of learning. That is why I tailor my lessons to your needs. I am always involved in your progress and am optimistic and approachable by nature. During the lessons I often notice that students not only understand the material better, but also their self-confidence grows. Besides being a tutor, I am a part-time artist (painter and musician). My creative background gives me a fresh and enthusiastic perspective on science subjects. If science subjects feel hard, difficult or boring, or if you had a teacher who couldn't make it fun, I can help you change that. The more you understand, the more fun it becomes, and good grades will follow! I'd love to meet you!
