you were actually identifying it!
hydrogen and oxygen gases are written as H2 and O2.
that the tube with H2 filled up twice as fast as the tube with O2?
Looking at the BALANCED reaction to the left, do you see WHY?
that is as simple as the test for hydrogen?
Most of the elements are solids
but hydrogen exists as a gas at room temperature (20 degrees C).

Imagine that this proton child
has a wooden paddle with a rubber ball
attached to an elastic string.
Think of the ball as an electron.
Watch as this proton child creates
a spherical space around himself
by hitting the rubber ball which travels
outward in all directions.
There would be a whole space surrounding the child where the ball would bounce in and out, a spherical region you would avoid. So it is with atoms!
