When an atomic nucleus emits an alpha particle it decay into an atom with atomic number 2 less and mass number 4 less. Thus Thorium 230 decay as follows.
230 90Th -------> 226 88Th + 4 2 He
thorium is in the atomic number 90 thus it during alpha decay it reduces to atomic number 88 while its 230 mass number reduces to 226
This is a plant cell because there are chloroplasts in this diagram which are present in plant cells
For any element the nucleus consists of neutrons and protons while electrons orbit around the nucleus, (3)
