Almost none in most countries where it is mined. This ore may be found associated with old salt pans, and is mined in many countries. Its metals are tantalum and niobium. Tantalum is a very useful material used in making capacitors.
The three main isotopes of niobium are niobium-93, niobium-95, and niobium-96. These isotopes are stable and occur naturally in different abundances. Niobium-93 is the most abundant isotope, followed by niobium-95 and niobium-96.
Tantalum doesn't exist in pure state in nature.
The United States of America holds the most overseas land of any country.
Tantalum has 73 protons, 73 electrons, and isotopes of Tantalum include a varying number of neutrons. The most common isotope, Tantalum-181, has 108 neutrons.
Probably the USA.
41 protons 41 electrons 52 neutrons
there are many, not one country holds that title, when a country is a democracy, that is IT.
Japan holds $6billion and UK holds $2billion.
Most people are from China, which holds about 18.5% of the world's population.
