You must have used "Name" rather than "FullSymbol" to get the name.
However, use "StandardName" vice "Name" for use in subsequent

IsotopeData["Np239", "Name"]


sn = IsotopeData["Np239", "StandardName"]


IsotopeData[sn, "DecayModes"]

{"BetaDecay", "AlphaEmission"}

IsotopeData[sn, #] & /@ %

{True, True}

Presumably you meant "AlphaEmission" rather than "AlphaDecay"

MemberQ[IsotopeData["Properties"], "AlphaDecay"]
