AntimatterIS MORE EXPENSIVE BUT MOST EXPENSIVE IS OSMIUM AND TANTALUM
The price of technetium is approx. 50 US $/g.
Antimatter
Technetium and Rhodium.
well, i think yes. Antimatter is produced when high energy particles collides like when cosmic rays impacts with the earth's atmosphere. Antimatter will immediately annihilate when it comes in contact with matter so it's almost impossible to collect. But antiparticles can be created artificially in the cyclotrons like in the ATHENA project at CERN. another challenging problem is how to store antimatter, the Penning Trap (used for charged particles) and the atomic trap(used for uncharged particles) are specialized device to store antimatter. running the CERN is costing billions of dollars. estimations points to 62.5 trillion dollars to produce 1 gram of antimatter. so far, i think it would be the most expensive substance ever made.
Technetium is not abundant. Compounds of Tc are most used.
Technetium has become less expensive due to advancements in nuclear technology, specifically the development of more efficient methods for producing it in nuclear reactors. Additionally, increased supply from reactors and recycling programs have helped reduce the overall cost of technetium production.
Antimatter is an extremely rare and expensive substance to produce. Estimates suggest it can cost billions of dollars per gram to produce antimatter. Its high cost is due to the complex processes required to create and store it.
Antimatter is extremely rare and expensive to produce, estimated to cost trillions of dollars per gram. However, it is difficult to assign a specific monetary value to antimatter as it is not commercially available for sale.
If we didn't have technetium, certain medical imaging procedures like bone scans and heart stress tests would be more challenging as technetium-99m is commonly used in nuclear medicine for diagnostic imaging. Alternative isotopes or imaging techniques would need to be developed, which could be more expensive or less effective. Additionally, research in nuclear physics and related fields may be impacted due to the unique properties of technetium for studying nuclear structure and reactions.
The price of technetium has gone down because there wasnt much technetium in the 1950s which made it rare and expencive but now there are more power stations now than there was before which produce technetium so there is more about and has reduced in price.
Technetium has protons, neutrons and electrons. It also happens to be radioactive. For more information on it go here: http://en.wikipedia.org/wiki/Technetium
If such a device could be made, it would be a lot more powerful than a nuke of similar size, as ALL the mass of the antimatter and neutralising matter would be anhialated and turned to energy, instead of a small fraction of total mass of uranium, plutonium etc. Currently not a real threat to the world as antimatter is extremely expensive to produce and the total amount manufactured to date would only power a 60 watt light bulb for a few hours, and cost $ billions to produce. Ds1ao: with on gram of antimatter you can make a 43 kiloton bomb (more than three times as powerful as the bomb dropped on Hiroshima
