What element has less than one halogen existing on the earth?

Any element, other than a halogen is - by definition - not a halogen and so it does not have a halogen and that is less than one halogen.

Why can an element have the same atomic mass as another element?

Two elements can have the same atomic mass if one has more or less neutrons than protons in the nucleus. These are called isotopes. not much to im prov thank you


What is the element with the least atomic mass is hydrogen or helium?

Hydrogen's atomic mass (1 amu for the most stable isotope) is less than that of helium (4 amu).


What contains a halogen?

A halide is a compound consisting of two parts; a halogen and another electronegative element. The mostcommonhalogens arefluorine(F),chlorine(Cl),bromine(Br),iodine(I), andastatine(At). If put together with another element, they formfluoride,chloride,bromide,iodide, orastatide. Therefore, your question is not right since a halide consist of elements and one element can only be a halogen or non-halogen. (halogen and halide are two different things)
