Graphite is a good reflector. In graphite moderated gas cooled reactors an extra layer of graphite is provided surrounding the core which helps to reflect neutrons which would otherwise escape, back into the core.
Glass, clear plastics, perspex, most gases
Yes, protons and neutrons.
Protons and neutrons have almost the same mass.
(The constituent particles of an atom are the electron, the proton and the neutron; all three are fermions. However, the hydrogen-1 atom has no neutrons and the hydron ion has no electrons.) WIkipedia
A Material Takeoff is the process of analyzing(this includes list of materials with quantities and types,grades of materials and the weights of such materials) drawings and determining all the materials required to complete the design. A Bill of Materials is adocument that shows detailed desgriptions of materials used in completing a project,this includes,types of materials,specification of each item,gost of each item used,number and cost of labour used in completing the poject. The major difference between the two is:MTO is needed to make a BOM,a BOM aids in the procurement and requisition of materials.
Uranium atoms (and oter fissionable materials) absorb neutrons, which cause the atoms break apart, resulting in two fission products, two or three more neutrons, and alot of energy in the form of heat. This heat turns water into steam, and this steam drives a turbine, which drives a generator, which produces electricity.
Carbon and glass fiber are two materials that are required for composit making.
Two materials that do not get hot easily are stone (such as granite or marble) and glass. These materials have high thermal mass, meaning they can absorb heat without getting hot quickly.
Used by Rutherford in his experiment made of two protons and two neutrons are alpha particles. Rutherford discovered the nucleus using his gold foil experiment.
Two isotopes have two neutrons: 3H and 4He.
The atomic particles that make up an alpha are two protons and two neutrons. The subatomic particles are contained within the neutrons & protons and there are too many to list here, plus I don't know all of them.
It is helium, specifically the helium-4 isotope, that is composed of two protons and two neutrons.
An alpha particle is composed of two protons and two neutrons.
alpha ray Stream of particles containg two neutrons is, I believe: Alpha Ray
A helium atom typically has two neutrons. This gives helium a total of four particles in its nucleus (two protons and two neutrons), which contributes to its atomic mass of approximately 4 atomic mass units.
Helium has two protons, and, in its neutral state, two electrons. It can have either one or two neutrons.
An alpha particle consists of two protons and two neutrons.
