Are the nuclear reactors the same processes occurring in the sun and reactors?
No. The sun produces energy by fusion. It is joining hydrogen atoms into larger helium atoms, which releases energy. Man-made nuclear reactors produce energy by fission. They break large atoms into smaller atoms, which also releases energy.
Why don't H2 and O2 react as soon as they mix?
The activation energy barrier. Combining H atoms and O atoms into water releases a large amount of energy, but breaking up H2 molecules and O2 molecules into H and O atoms requires a large (but not as large) amount of energy. You need to supply sufficient energy to get things started, after which it's generally self-sustaining (and very rapidly so; a stoichiometric mixture of H2 and O2 is quite explosive once ignited).
When hydrogen changes into helium does it explode as fiery energy?
The fusion of two hydrogen atoms yielding a helium atom expels a large amount energy.
What are the products and reactants in the primary fusion reaction carried out within the sun?
The reactants are Hydrogen atoms and products are Helium atoms. Because Helium atoms are larger than Hydrogen atom, large amount of energy is released from the net binding energy that resulted during the fusion process.
How does nuclear fusion differ fundamentally from nuclear fission?
nuclear fusion is when two atoms are forced together, fusing their nuclei into a heavier element and releasing a large amount of energy. Fission is when an atom is broken up into smaller atoms releasing a large amount of energy.
Which element's second ionization energy level is large compared to its first ionization energy?
Cl
The atoms of the most active non-metals have?
large atomic radii and low ionization energies
Which has lower ionization energy an atom with a small radius or an atom with a large radius?
Lower ionization energy would be associated with the larger atom, as the outer most electrons would be further from the nucleus, and not held as tightly.
Are the nuclear reactors the same processes occurring in the sun and reactors?
No. The sun produces energy by fusion. It is joining hydrogen atoms into larger helium atoms, which releases energy. Man-made nuclear reactors produce energy by fission. They break large atoms into smaller atoms, which also releases energy.
How is nuclear energy sustainable?
nuclear energy is produced by taking advantage of natural decay in large nuclei of atoms. atoms with large enough nuclei can only be produced by very large scale nuclear fusion such as stars during a supernova, and making it on earth would take enormous amounts of energy. So no, nuclear energy is not totally sustainable, but a small amount of fuel lasts a long time. For this reason energy can be stored by scientifically making large nuclei atoms and utilizing them later.
How are charges developed in the Large Hadron Collider?
Like most high energy accelerators, the LHC begins the ionization process with Cockcroft-Walton Generators.
Energy that lies at the level of atoms and does not affect motion on a large scale is sometimes called?
How is called the energy that lies at the level of atoms and does not affect motion? Its nonmechanical.... Do you go to PH???
What is nucear energy?
I guess you mean "nuclear energy". That's a collective term for nuclear fusion (combining light atoms into heavier atoms), and nuclear fission (splitting heavy atoms). Both processes can release large amounts of energy, in some cases.
Elements on the side of the periodic table require large amounts of energy to remove an electron from the outermost energy level of their atoms?
Elements on the right side of the periodic table require large amounts of energy to remove an electron from the outermost energy level of their atoms. It is much easier for them to gain rather than lose electrons.
What causes energy to be released inside the sun?
A fusion of hydrogen atoms forms helium and formes a large amount of mass into energy.
Which of the following is an example of nuclear fission?
A large radioactive atom breaks into smaller atoms, producing nuclear energy.
Why do elements at the bottom left of the periodic table have low ionization energies?
Bottom left elements of the periodic table have low first ionization energies. Ionization energy is the minimum energy required to remove the outermost electron from an isolated gaseous atom to covert it into monovalent ion. Ionization energy depends on the electrostatic force of attractionbetween the nucleus of the atom and the outermost or valence electron. More the attraction more the energy needed.First of all the size of atoms of bottom left elements is larger as compared to other elements. Therefore, the electrons in the valence or outermost shell are at large distance from nucleus and feel less electrostatic force of attraction and are easier to remove. With increase in atomic number the number of inner shells of electron increases as a result of which shielding or screening effect increases. Since these elements have more number of inner shells so screening effect is more which further decreases the force of attraction. However, the high nuclear charge should cause more attraction but combined effect of nuclear charge, screening effect and large distance from nucleus result in decrease in attraction. Decreased attraction means it will be easier to remove valence electron and ionization energy will be low. It should be noted that only first ionization energy in case of group 1 elements and first and second ionization energy in case of group 2 elements is low but once the atoms of these elements acquire noble gas configuration by losing electrons their ionization energy becomes unusually high.
