Silver is an uncommon metal element that is mostly used decoratively and in jewellery. Though it is used in solar panels, water filtration, circuitry, and in radio and radar technologies. It has the lowest contact resistance and highest electrical conductivity of any known metal, and its applications are getting more widespread within the computer electronics and electric generation industries.
Foxes are a versatile candid like animal, though some are more closely related to voles than dogs they are my favourite creature bar none. The common phrase “a silver fox” is pretty much all it took to get its association with this element but I’m sure you can find plenty more.
The Golden Eagle is a common bird of prey that lives all round the northern hemisphere. It’s much like Cadmium in its commonality. It preys small rodents, occasionally other birds and carrion.
Cadmium is often a byproduct of the zinc refining process and is used in glass plating and used to be used in batteries. Cadmium is somewhat toxic and has some long-lived isotopes and can be bio reactive causing damage to cells and cancer in fallout post-nuclear bombs or meltdowns.
