It depends on what elements it combines with and in what arrangement. There are many compounds of arsenic.
Helium
yes
it depends on wht compound it its
A compound is 2 elements chemically combined, though it is unseparatable, it is made up of 2 or more elements. But since a compound cannot be broken down into elements, after the elements are chemically combined, that makes a compound a pure substance
Gold is a very soft element which is combined with other elements to become hard. A pure gold jewel floats in water while a gold combined with other elements become densier.
Helium is inert and doesn't react with any other elements.
