Nuclear fusion in the sun involves hydrogen (H) atoms
combining to form helium (He). A student claims that since the atmosphere

chain reactions can only happen during nuclear fission.
Metals generally form cations, meaning they become positively charge - this positive charge is due to the loss of electrons.
