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.

Compound or substance: a molecule containing two or more types of chemical elements.
When two or more elements are combined, it is known as a compound. Compounds are formed when elements chemically react with each other to create new substances with unique properties.
That's because of the way "compound" is defined. If atoms of an element combine with other atoms of the SAME element, then it's not called a "compound".
Compound- two or more elements bonded to each other in definite proportions NaCl is a compund
