What else can I help you with?
Which category almost never reacts with the other elements?
Alkaline earth metals
What are some useful applications for the colored flame produced when alkali and alkaline earth elements are heated?
i need this answer too...
What are the rare earth elements?
The rare earth elements are 17 proper elements, consisting of scandium, yttrium and the fifteen lanthanoids.All of the elements in the lanthanide and actinide series are considered "rare earth" elements
What is another name for the rare earths?
alkaline earth metalsANSWERThe rare earth elements are scandium, yttrium and the 15 elements in the lanthanide group.
What elements does the earth and moon have that are the same?
rocks
Elements found on earth have much to do with?
supernovae
Why can't elements be produces in the Earth's atmosphere?
Elements are not produced in the Earth's atmosphere because they are formed through nuclear fusion processes in stars or supernovae. The elements found on Earth were created during these events and then dispersed into the universe, eventually coalescing to form celestial bodies like planets.
What produced the iron and heavier elements like gold and silver in the Earth's core and crust?
evry element in the periodic table above hydrogen is produced by nuclear fusion in the cores of a star, upto and including iron, afte iron the energies required to fuse iron are not obtainable at the pressures and temperatures in a stars core even though they are massive, the heavier elements are produced during a supernovae were the blast shockwave forces the atoms so closr together and thus generates such incredible temperatures and pressures that iron is forced to fuse with itself and lighter elements so producing the rest of the elements which are then scattered throughout the local area as cosmic dust which can go on to form future planets like our own earth.
How is a supernova related to matter found on earth?
A supernova is a star that explodes. Stars about the size of our Sun explode when they run out of "fuel". The fuel they have is Hydrogen which they fuse into Helium and thus convert mass into energy (they shine brightly), Then the Helium and some Hydrogen are fused into heavier elements (Lithium etc) making more energy. All elements heavier than Carbon and lighter than Iron are made in the supernova explosion that comes at the end of the star's "life". Heavier stars will make even heavier elements. The Earth is mostly made of these heavier elements. We are all stardust.
What is the origin of Tungsten?
Tungsten occurs naturally on Earth. It is expected to have been produced by the same supernovae that produced our other heavy elements. It was first identified by Johan Gottschalk Wallerius in 1747. There are mines in Europe and China that produce most of it. A few mines in North and South America. I hope I guessed which "origin" you intended...
Why are supernovae essential for our existence?
Supernovae are essential for our existence because it distributed elements heavier than helium (those heavy elements are created in the star that later became the supernova) into the space. Those elements include carbon, oxygen, calcium, iron, iodine, and much more. Without those heavy elements, the Earth would not exist as a rocky planet, and essential elements for life would also not be available.
Why are technetum promethium and neptunium considered naturally occurring elements even though they are not found on earth?
Technetium, promethium, and neptunium are considered naturally occurring elements because they are produced through natural processes like nuclear reactions in stars and supernovae. While they may not be found in abundance on Earth due to their short half-lives, they have been detected in trace amounts in certain geological formations or meteorites.
Why can elements be produced in the sun but not in earths atmosphere?
Elements can be produced in the sun through nuclear fusion reactions that occur due to the intense heat and pressure. These conditions are not present in Earth's atmosphere, which is why elements are not produced there. Earth's atmosphere primarily consists of gases and does not contain the necessary conditions for nuclear fusion to occur.
Can gold be created on earth by a fusion reaction?
Gold can be created on Earth through nuclear reactions, such as the fusion of heavier elements in the core of supernovae or in particle accelerators. However, the amount of energy required to produce gold through fusion is currently much higher than the value of the gold produced, making it not economically feasible.
Did supernovas exist before life on earth?
The first supernova was probably about 450 million years after the big bang, when the first, massive stars (Population III stars) exploded filling the Universe with the first heavy elements. These elements were "absorbed" by population II stars, which again exploded as supernovae. These metal enriched stars populated the Universe with the rest of the known elements. So supernova were around well before life on Earth. In fact without supernovae there would be NO life on Earth.
Why can elements be produced in the sun but not in Earth's atmosphere?
Elements can be produced in the sun through nuclear fusion reactions, which require extremely high temperatures and pressures. These conditions are not present in Earth's atmosphere, so elements are not produced in the same way here. Elements on Earth are primarily produced through processes like supernova explosions and nuclear reactions in labs.
How are gamma rays produce on earth?
Gamma rays are produced on Earth through various processes, such as radioactive decay of certain elements, particle interactions in high-energy astrophysical phenomena like supernovae and black holes, and in artificial sources like nuclear reactors. They are the most energetic form of electromagnetic radiation, with wavelengths shorter than X-rays.
