Three metals, P, Q and R, are tested with compounds of other metals. The results are shown in the table.
| Test | Observation |
|---|---|
| P added to a compound of Q | Q forms |
| Q added to a compound of R | R forms |
State which metal is the most reactive.
Predict whether R displaces P from a compound of P. Explain your prediction in terms of the electrons lost by the atoms.
