how reactive are transition metals compared to group 1

Answers
Transition metals are much less reactive than group 1. Group 1 metals react with oxygen on contact with air and are therefore stored in oil. They appear dull (this is the oxide layer) but are shiny inside if you cut them open. Group 1 metals also react vigourously with water, this reactivity increases as you go down the group. Transition metals however are not that reactive in comparison. They react with oxygen but only when heated, and can therefore be stored in air without corrosion. Some metals do corrode eventually, iron being the best example. Iron forms iron oxide (rust) when exposed to air and water, but this reaction happens over time. Transition metals do not react with water.
