Astatine
The element with less than one ounce existing on Earth is astatine. It is a rare halogen element and is primarily produced through artificial means due to its scarcity in nature.
Hydrogen is not classified as a halogen. Halogens are a group of elements on the periodic table that includes fluorine, chlorine, bromine, iodine, and astatine. Hydrogen is a nonmetal element that belongs to a different group on the periodic table.
When a halogen atom gains an electron, it forms a halide ion and releases energy in the form of heat or light. This process is exothermic and results in the formation of a stable, negatively charged halide ion.
NOTHING!
Nothing . . . there is no element with the symbol, "T".
A possible rhyme for ytterbium could be "premium" or "aquarium."
Francium. Oh, and you spell it Halogen :)
