Generally, Hydrogen has the lightest mass in the whole periodic table. so it is less dense then the surrounding air and it will float.
A balloon filled with air will have gases like oxygen, carbon dioxide etc... all in an enclosed space. Logically, the weight will add up and so it becomes more heavier and becomes more dense then its surroundings.

Hydrogen filled balloon goes up due to buoyancy as hydrogen is lighter than air.

Hydrogen is less dense than air. In fact, it is sufficiently less dense that the total mass of a balloon filled with hydrogen (including the mass of the balloon itself) is still less than the mass of a volume of air equal to that of the inflated balloon. As a result, the buoyant force is greater than the force of gravity, and the net force is upwards.
A balloon filled with air has a greater mass than an equal volume of air, because the air inside the balloon clearly has a mass equal to that volume of air, while the material of the actual balloon is more dense than air. As a result, the force of gavity is greater than the buoyant force, and the net force is downwards. However, the fall of the balloon is significantly slowed by the buoyant force.

The mass of hydrogen is less than air. Air which is composed of oxygen, CO2, argon, nitrogen, etc. has an average mass which is much greater. therefore the hydrogen balloon floats, while the air balloon sinks. It cannot overcome the weight of the balloon itself to remain stationary.

Hydrogen is lighter than air and so it rises.

air is mostly nitrogen (about 78%) the rest is oxygen etc... Hydrogen is much ligheter than oxygen and slightly more bouyant than nitrogen. therefore it will rise. light materials float to the top in water and in the air.
