In radioactive decay, u must acknowledged that there 3 are type of decay that we learned in SPM.
1. Alpha decay (He 4/2)
2. Beta decay (e 0/-1)
3. Gamma decay
For each decay, u must be able to define it & write the equation in order to balance the nuclide notation before & after reaction. The concept is simple, all u need is make sure that the total nucelon & proton number before the decay, must be equal to the one after the decay.
For further details on radioactive decay,u can check this out!
U should try some questions on this topic especially the one using the graph of nucleon number vs proton number. Enjoy your revision!
About Me
- Cikgu Ahmad
- I am a full time specialist Physics tutor operating in Klang Valley. I've been educating student for more than 10 years. My specialty is to transform student that had failed their physics subject into a better result. Even some of them managed to get an A in their final exam, You can read their testimony in this blog. I provide home tuition for physics subject to those living nearby KL especially around W.Maju, Ampang,Melawati and Setiawangsa. At the same time i 'm giving online tuition to all malaysia & overseas student. For tuition centre looking for a physics tutor, i'm also able to give seminar and conduct weekly classes. Meanwhile,for school teachers who are organising physics seminar, i am happy to assist u in that aspect. If u have enquiry on my service, do contact or whatsap me at 017-2877589 or email me at celikfizik @ gmail . com
