Hydrogen. You could have found this out yourself had you just looked at a Periodic Table of elements.
Not everyone knows what tools to use to find out answers to their questions, using wiki.answers.com is one of the best ways to learn what you want.
Hydrogen is the least massive element. It is found in group 1, period 1 on the periodic table.
All elements , except the trans-uranic(Actinides) are atomically stable. The Actinides being the most massive elements are unstable and spontaneously breakdown into smaller less massive elements. The most massive element that is atomically stable is 'lead' ( Pb ; Plumbum).
Orbitals don't contain elements. The elements each have specific orbitals based on the number of electrons it has. All of the elements have at least one s orbital. Hydrogen being the simplest element has one electron in the 1s orbital. The s orbital can contain a maximum of 2 electrons.
Yes, all matter on earth contains at least one element, and all elements are found in the periodic table.
A compound consists of at least two elements chemically bonded together.
Mercury is the smallest planet in the Solar System
Hydrogen is the least massive element. It is found in group 1, period 1 on the periodic table.
Mercury is the least massive of all the planets. The least massive planet is Mercury (0.055 Earths). However, the planet with the weakest gravity is Mars. I am of course not treating Pluto as a Planet (as it is no longer categorized as a planet), if I were to count Pluto then it would be the least massive ( 0.0021 Earths).

Hydrogen is the least dense of all the elements and all other known substances.
I Say Mercury.
It is believed that the air elements (Aquarius, Gemini, Libra) are believed to be the least attached of all the elements. However, that does not mean that they are not affectionate.

No. Only the most massive stars can fuse iron.
least - electron most - the top quark
That's not true. All sets have zero or more elements. You can have a set with zero elements - the "empty set".
All elements are made up of individual atoms. There are no exceptions. An element of something must be represented by at least one atom of that substance.
