Chemistry Help: Identify Alpha Decay, Beta Decay, or Fusion

[LittleMiss]

Look At each nuclear equation below and identify whether it is alpha decay, beta decay, or fusion.

a) Thorium-234->Proactinium-234+-1^°e
I put Beta decay for my answer.

b) Hydrogen + Hydrogen -> Helium
I answered Fusion

c)Uranium-238->Thorium-234+Helium-4
I answered Alpha Decay

I would like to know if I'm correct in my answers.
