2.what metals are used in the alloy to make 50p coins
3.the equation 50+82+29+51 adds up to 212 but what has this answer to do with metal?

[halcyon days]

1. coypu
2. copper/nickel
3.Pewter

50p coins are an alloy of Copper and Nickel, but I do not see how that is related to mammals

[pjgriffo]

a coypu is a mammal - type of beaver (animal!!)

[ladyalex]

So how does that relate to Copper (Cu) and Nickel (Ni) ?

I think this must be 2 separate quizzes - mammals & metals

Halcyon days is right about pewter. It is an alloy of tin ( atomic number 50), lead (82), copper (29) & antimony (51)
