{'metals': [1, 2, 2, 7], 'copper': [1, 0, 1, 1], 'hydrogen': [0, 0, 1, 3], 'mercury': [0, 0, 2, 2], 'silver': [0, 0, 0, 1], 'tin': [0, 0, 0, 1]}

The question asks us to identify the metal that is more reactive than hydrogen. The reactivity of a metal is determined by its ability to lose electrons and form positive ions.

Option 1: Mercury

Mercury is not more reactive than hydrogen. It does not readily lose electrons and is relatively stable.

Option 2: Copper

Copper is not more reactive than hydrogen. It does not readily lose electrons and is relatively stable.

Option 3: Silver

Silver is not more reactive than hydrogen. It does not readily lose electrons and is relatively stable.

Option 4: Tin

Tin is the correct answer. Tin is more reactive than hydrogen as it readily loses electrons and forms positive ions. It is classified as a moderately reactive metal.

In conclusion, among the given options, only tin (option 4) is more reactive than hydrogen.
