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.
The atom at the top left of the periodic table would have the least mass. Hydrogen, the first element, has the lowest atomic mass among all the elements.
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.
Yes. All naturally occurring elements in the universe can be found in most stars, though generally only in small concentrations. Massive stars that have depleted the hydrogen in their cores may start producing elements as heavy as iron.
Mercury is the least massive of all the planets in our solar system.
The atom at the top left of the periodic table would have the least mass. Hydrogen, the first element, has the lowest atomic mass among all the elements.
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.
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.
No. Only the most massive stars can fuse iron.
Electrons are the least massive particles in an atom. They have a mass that is about 1/1836th the mass of a proton or neutron.
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.
That's not true. All sets have zero or more elements. You can have a set with zero elements - the "empty set".
Yes, all matter on earth contains at least one element, and all elements are found in the periodic table.
