Hydrogen. You can test it by putting a burning splint over the test tube, it should pop. I'm not sure if this is true most of the time, but it is true for many metals.
True
Most metals are reactive to some extent, but their reactivity varies. Some metals, such as gold and platinum, are less reactive and do not easily tarnish or corrode. Other metals, like sodium and potassium, are highly reactive and must be stored in oil to prevent them from reacting with moisture in the air.
yes the most chemically reactive elements are in group 1
