Open in App
Solution
- Alpha particle is a positively charged particle consisting of 2 protons and 2 neutrons bound together.
- So the weight will be 4 times as that of a proton (proton and neutron has approximately equal weight).
- Thus their sum weight will be 4.001 amu.
- Therefore, the weight of alpha particle is 4.001 amu.
