Berkelium and nobelium are members of the actinides group, solid metals, radioactive elements, unstable elements, artificial elements, very difficult to prepare extremely small quantities, only some compounds are known, etc.
Nobelium has no uses, it is only for research.
Hydrogen can react with practically all other elements.
