They freeze. Liquid hydrogen is very cold.
If the density of a solid substance is greater than that of the liquid it is placed in, the solid substance will sink to the bottom of the liquid. This occurs because objects with higher density will displace an equal volume of the lower density liquid, causing the solid to sink.
When a liquid is placed under pressure, its volume decreases slightly due to the compressibility of the liquid, although most liquids are relatively incompressible. Increased pressure can also raise the boiling point of the liquid, allowing it to remain in a liquid state at higher temperatures. Additionally, if the pressure is released suddenly, the liquid may vaporize or form gas bubbles, depending on the conditions.
Hydrogen hasn't metallic properties.
Properties of Hydrogen. Hydrogen is a nonmetal and is placed above group in the Periodic Table because it has ns1 electron configuration like the alkali metals.
If a split that is on fire is placed into a container containing hydrogen gas and oxygen gas, the split will react with the hydrogen and oxygen gases causing a combustion reaction. This reaction will produce water vapor and release a large amount of heat and light. It can result in an explosion due to the rapid combustion of hydrogen and oxygen.
They float.
If the density of a solid substance is greater than that of the liquid it is placed in, the solid substance will sink to the bottom of the liquid. This occurs because objects with higher density will displace an equal volume of the lower density liquid, causing the solid to sink.
An object will float if it has less density than the liquid in which it is placed.

When a liquid is placed in a closed container, molecules with sufficient energy can escape from the liquid and turn into gas. This process is called evaporation.
AAt
The sinking objects share the characteristic of being denser than the liquid they are placed in, causing them to sink rather than float.

If the density of a body is greater than the density of the liquid it is placed in, the body will sink in the liquid. This is because objects with higher density than the liquid they are placed in will experience a net downward force greater than the buoyant force acting on them, causing them to sink.
When charged objects are placed near neutral objects, there can be a transfer of electrons between the objects, resulting in the neutral object becoming charged. The charged object can induce a separation of charges in the neutral object, causing it to attract or repel other nearby objects.
