When the atomic nuclei of a pair of aluminium nuclei are fused the element produced is?
You cannot fuse two lithium atoms, the immediate product of high energy collisions of lithium nuclei are alpha particle showers and some neutrons.Li6 + Li6 --> He4 + He4 + He4Li6 + Li7 --> He4 + He4 + He4 + nLi7 + Li7 --> He4 + He4 + He4 + 2n

How you differntiate He4 and He3 fragments in relativistic heavy ion collisions?
As regards 3He and 4He, they both have the same charge, which will be the +2 derived from the two protons. But 3He has only the one neutron, while 4He has two neutrons, and is heavier. We can use their different masses and identical charges to differentiate them in a detector. If both particles are moving away from a collision event they'll move through our detector. We include a static (fixed) magnetic field with our detector, and that way the charged particles will have to move through it. The charges of the particles cause them to create tiny magnetic fields around their path of travel (as is true of all charged particles), and this magnetic field will interact with the fixed field of our detector. The interaction of the two fields, the fixed one and the one generated by a particle, will cause the particle to be deflected and to travel in a curve. See what's coming? Both 3He and 4He will be deflected and their path of travel will curve. Their charges are the same, so the same force will be acting on each one, but the heavier 4He will be deflected less than the 3He, and we'll be able to figure out which is which. The 3He will take a path with a tighter curve than the one carved out by the 4He. Positive charges will curve in the opposite direction as negative charges, naturally. Sorting things out in the detectors can be tricky, but this in an approach that is pretty standard.
How many atoms are in He4?
He4 would contain four atoms, if it were possible for helium to combine that way.4He (which is pronounced "helium four") is a single atom, with the 4 being the number of nucleons (and thus the approximate atomic weight).
How do you reverse the door on Kenmore HE4 dryer?
To reverse the door on a Kenmore HE4 dryer, first, unplug the appliance and remove the screws from the door hinge on the side it currently opens. Then, carefully detach the door and reattach it to the opposite side using the screws from the original hinge. Make sure to transfer the door latch and any necessary components to the new side. Finally, check that everything is secure and test the door operation before plugging the dryer back in.
What is going through fusion inside the sun to make helium?
The fusion process of hydrogen to helium in nature is the one that powers stars. The net result is the fusion of four protons into one alpha particle, with the release of two positrons, two neutrinos (which changes two of the protons into neutrons), and energy, but several individual reactions are involved, depending on the mass of the star. For stars the size of the sun or smaller, the proton-proton chain dominates. Two sets of two separate 1H protons fuse into two sets of a 1H proton and 2H proton-neutron while (both sets) release a neutrino and a positron. The resulting two 1H proton and 2H proton-neutron sets fuse into two atoms of He3 (2 protons and a neutron) while emitting gamma radiation. In the final stage the two He3 atoms fuse into a single He4 (2 protons, 2 neutrons) atom while emitting 2 H1 protons.
What equation correctly represents alpha decay of polonium 214?
The equation for the alpha decay of 210Po is: 84210Po --> 82206Pb + 24He representing the alpha particle as a helium nucleus. 206Pb, the daughter atom, is stable.
How did Kevin Love become famous?
Kevin Garnett became famous when he4 began playing basketball in the NBA. As of 2014 he plays the position of power forward for the Nets.
What is the superscript 4 for helium?
4He or He4. 4 stands for the mass number of Helium Mass number = number of protons + number of neutrons Since the atomic number or number of protons in helium is 2, the number of neutrons in He-4 is also 2.
Is the HGC test also used for ovarian cancer?
The HGC test, or human chorionic gonadotropin test, is primarily used to detect pregnancy and certain types of tumors, including gestational trophoblastic disease and some germ cell tumors. While elevated HCG levels can sometimes be seen in ovarian cancer patients, it is not a standard marker specifically for ovarian cancer. More commonly used markers for ovarian cancer include CA-125 and HE4. Therefore, while HCG may provide some information, it is not typically used as a primary diagnostic tool for ovarian cancer.
How does nuclear fusion in the Sun create new heavier elements?
Smaller nuclei fuse to become larger ones. The sun is mostly hydrogen and helium. This is how stars start out. They make energy by squeezing the hydrogen nuclei together till they stick: - two simple hydrogen (H1) nuclei (protons) get stuck into a Deuterium (H2) nucleus. One proton turns into a neutron by absorbing a nearby electron (the two atoms each had an electron to start with but see below). - the Deuterium nucleus gets another proton stuck onto it and becomes either Tritium (H3) or Helium 3 (He3). Another proton will make it He4 which is regular helium. (or maybe H4 or Li4 but they decay into He4. He4 fills out the inner orbital so it's really stable.) - and so on and so on. As a star gets older, it starts having more He and Li and Be and heavier elements from this process. If there's enough helium or Lithium, they'll start fusing with each other and make even bigger nuclei, faster. At each step, energy comes off because it's in a lower energy state - like magnets that are stuck together instead of apart - but in the case of nuclei, it's the Protons that attract the Neutrons and vice versa, thru The Strong Force. But at the same time, all the protons are repelling each other! They're both + charged! Also, if they're cold atoms like you find on earth, they each have electron shells 100,000 times bigger than the nucleus, like a sand particle being suspended in the middle of a big balloon, so two neighboring atoms never get close enough to fuse. To make it stick together, you have to get the protons and neutrons close enough for The Strong Force to kick in and overwhelm the proton-proton repulsion. Fortunately in the sun, it's so hot (the atoms and atom pieces are flying around so fast) that the electrons have been totally ripped off their nuclei and fly around free with the nuclei - that's called a Plasma. If two protons or other nuclei manage to stumble into each other hard enough, they'll fuse. As time goes on, heavier and heavier nuclei form. Unfortunately these reactions require more compression and heat. Gravity is still working, so the nuclei keep fusing. the biggest the nuclei become is around where Iron is on the list of elements. At that point, there's no energy coming off at all- it's sortof an energy valley and this is the lowest point. The star becomes a white dwarf, or explodes as a supernova and the core becomes a neutron star or black hole, depending on how big it is. Heavier nuclei are made either when the star explodes as a supernova, or by a process in red giant stars. The sun is too small for either of these two to happen. The heavy elements on earth are assumed to come from some other supernova like 5 billion years ago.
Why did hydrogen and helium leave earth's atmosphere?
There's a more scientific way to explain it but heres a simple one; If you have a balloon filled with helium where does it want to go? Up because its lighter than air so earths gravity is having a lesser effect on it. SO if its not in the confines of the balloon it will keep going until it reaches the outer edges of the atmosphere, at this point it will slowly 'leak' off into space and it will do so first as its lighter than most other gases floating around in the upper atmosphere
