Atomic Decay

Atomic Decay

This webinar covers atomic decay, a key area of MCAT chemistry. You will learn about the different types of subatomic particles and various decay processes, as well as how to solve related math problems. You will also be introduced to the important medical applications of atomic decay, such as PET imaging.

At a glance


Essential skills

  • Solve atomic decay as a mathematical operation

  • Solve half life problems

  • Identify applications of decay, such as PET scans


Knowledge Fundamentals

  • The differences between protons, electrons, and neutrons

  • The differences between alpha, beta (+/-), and gamma decay


On the MCAT

  • Remember that the MCAT gives you a periodic table, so don't forget to reference it for atomic number and mass

  • PET imaging is an important application of atomic decay; it pops up in Psych/Soc and in relation to brain anatomy


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
