Does zinc rust in water?
Like all ferrous metals, zinc corrodes when exposed to air and water. However, zinc corrodes at a rate of 1/30 of that for steel. The zinc is protected by the formation of a patina layer on the surface of the coating. The patina layer is the products of zinc corrosion and rust.

Why is gold so soft?
Gold is called a heavy metal because of its high density, which comes from the fact that each of its atoms is individually very heavy. In contrast, gold atoms slide past each other relatively easily, which makes the metal soft and malleable.
Is gold heavier than lead?
Gold is much heavier than lead. It is very dense. Therefore gold weighs 19.3 times as much or (19.3 x 8.3 lb) about 160 pounds per gallon. Although gold has a density 19.3 times greater than water and is one of the most dense substances on Earth, there are substances with far more amazing densities.
What is the meaning of the name Plumbum?
