No, because it is common.
The elements known as alkali metals are found in group I
alkali metals
elements in groups 3-12 are transition metals
metals that do not react readily are known as inactive metals
The outermost, known as the valance electrons.
Painite has been described by the Guinness Book of World Records as the rarest gem mineral. As of early 2005 there have been eighteen known specimens that are all accounted for.
because without artifacts we wouldnt have known there were early peoples
From research to answer this... Yes. They are the rarest species of giraffe known to the world.
NO! The phoenix is NOT the rarest silly band. It used to be known as the rarest but it infact has been proven wrong. The rarest is the purple Egyptian Eye
metals are known to be a good conductor of heat and electricity.
The world's rarest primate is the Hainan gibbon. It's scientific name is "Nomascus hainanus". There are less than 30 known to be alive in the world.
The Guatemalan wallet is considered the rarest of all Myachis, though there is no definitive proof that this sack still exists. The rarest Myachi that is known to exist is the prototype sack, the "Silver Surfer". Only 3 were made and that was in 1999.
The rarest British Penny would be the 1954 Penny. There is one known to exist, maybe two, but there could be some doubt about the second.
The elements known as alkali metals are found in group I
yes metals are more common than non-metals
alkali metals
Group 1 on the periodic table, known as the alkali metals, are the most reactive group of metals. They all share the chemical property of having just 1 valence electron. First ionization energies for these elements is quite low, and as you go down the group from top to bottom it gets lower. The alkali metals are so reactive that they do not exist elementally in nature; only in compounds. Sodium and potassium are the most common. Francium is the rarest.
