Question

Choices: True,False. Select all that are True.
Fission reactions produce a lot of radiation, but alpha decays are fairly safe.

Only very massive nuclei will undergo fission but even light unstable nuclei can undergo alpha decay.

Alpha decay is spontaneous, known fission reactions require neutron absorption.

Fission releases energy, alpha decay does not.

One alpha decay can produce another alpha decay. Each fission reaction occurs in isolation.

All daughter nuclei in a fission reaction are much smaller than the parent. In alpha decay, one daughter nucleus must be close in number and mass to the parent nucleus
