What is made up of 2 or more elements?
A compound is made up of two or more different elements that are chemically bonded together. Each compound has a fixed ratio of elements and distinct properties different from its individual elements.
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.
Is there a element that is made two or more elements?
No. An element is made of only one kind of atom. A compound is made of two or more elements.
Heavy elements contain more protons or neutron?
Heavy elements generally contain more neutrons than protons. This is because as the number of protons increases in heavier elements, the strong nuclear force needs additional neutrons to help offset the repulsive forces between the positively charged protons. This results in a higher neutron-to-proton ratio in heavier elements compared to lighter ones.
What is nucleosynthesis used for?
Nucleosynthesis is used for creating elements more complex than hydrogen
What are some characteristics of stars that might account for the fact that some have more complex elements in their spectra?
Older age might account for it. As a star ages, it uses up the simplest elements (hydrogen . . . helium . . .) then starts fusing heavier and heavier elements. Our Sun will get to the point of fusing iron, which is pretty heavy, but the truly large stars out there will fuse elements much heavier than Iron. These heavier and heavier elements may account for some stars having more complex elements in their spectra.
What is disadvantage of water cooling system?
heavier and more complex
Is complex compose of two or more elements?
yes
What evidence suggests that some elements are more rare than others?
The abundance of elements in the universe is a result of nucleosynthesis processes in stars. Elements with higher atomic numbers are generally rarer because they are produced through more complex and less common fusion reactions. Additionally, supernova explosions play a key role in dispersing heavier elements throughout the universe, leading to their lower abundance compared to lighter elements.
Why should there be a connection between an element's configuration and its location on the periodic table?
All elements are derived from Hydrogen. In a star it is fused into Helium. When a star goes downhill towards exploding matter is condensed further. The results of super novas is the matter everything is made of. Adding protons, neutrons and balancing with electrons. All elements get heavier and more complex as you go across and down on the chart.
Are radioactive elements made in a laboratory?
What an interesting question. The answer is however complex.It is possible to make small amounts of some radioactive elements or radioactive isotopes of some elements in a laboratory (usually involving a nuclear pile or an accelerator). For instance the element Plutonium is made this way.(Other radioactive elements are produced naturally by the radioactive decay of heavier radioactive elements)However, making a radioactive element or isotope from scratch requires the application of an enormous amount of energy. The place where all elements heavier than the element Iron (Fe - Atomic number 26) are made is in stellar explosions, the death of stars 8 or more times more massive than our Sun, called "supernovas".It is in supernova explosions that the radioactive elements are made.
Why can the fusion of iron into heavier elements not support a star?
The fusion of iron into heavier elements cannot support a star because it requires more energy than it produces, leading to a loss of energy and the collapse of the star.
Compounds are made made of how many elements?
Two or more elements.
How do you end period faster?
Actually if you exercise more the heavier it is. Because I was at volleyball camp and on my period it made it heavier. 2.14.11 Exactly! Even though it made your period heavier, more blood left your body and ultimatley shortened your period.
Are more than 100 elements are currently unknown?
The unknown elements are... well, unknown. However, it seems unlikely that there are 100 elements in addition to the known elements, for stability reasons: in generalm terms, the heavier the nucleus, the more unstable it becomes.
How do elements differ from compounds, and in what ways are they similar?
Elements are substances made up of only one type of atom, while compounds are substances made up of two or more different types of atoms chemically bonded together. Elements are the simplest form of matter, while compounds are more complex. Both elements and compounds are pure substances, meaning they have a fixed composition and properties.
As heavier elements are formed by fusion a massive star expands into?
As heavier elements are formed by fusion in the core, a massive star will eventually exhaust its nuclear fuel and trigger a supernova explosion. This explosion will generate immense energy, leading to the production and dispersal of even more heavy elements into space.
