The nuclide Sn-128 is unstable. Which decays types would this nuclide be expected to undergo?

How can we know what kind of decay any nuclide would undergo when only the name of the nuclide is given? Are there any properties that can be used to identify the decay type (alpha-particle decay, beta particle decay (both positive and negative) , electron capture)? Is it possible for any nuclide to undergo more than one type of decay? If so, how can we identify that too?
