When B-10 absorbs a neutron, as you say it emits an alpha particle. This contains two protons so the other result is the element with two fewer protons than boron, which is lithium. So the process is starting with B-10 with 5 protons and 5 neutrons, add 1 neutron, then split into alpha which has two protons and two neutrons, and lithium which has three protons and four neutrons. The control rods have to contain enough boron to last the life of the reactor, unless they are to be replaced, which I don't think is needed. In the AGR gas cooled reactors the rods are made of boron steel alloy, in the light water reactors they are boron carbide.

A radioactive atom is an atom that has an unstable nuclear force, and therefore either absorbs or emits a radioactive particle.
This phenomenon is called phosphorescence.
If a "particle" (either a photon or an actual particle) strikes a molecule of air it will either be absorbed or will result in particles of less energy.
It is used in military shells and bombs to make them penetrate armour better (because it is heavy). It can also be used in breeder reactors to make plutonium for fuelling other reactors, though this has not been used on any commercial scale as yet.
When it captures (not absorbs) electrons and becomes neutral the alpha particle becomes a helium atom.
If boron-10 absorbs a neutron, it becomes boron-11. Boron-11 is stable and does not emit any particles. Please restate the question.

Boron is the most commonly used, cadmium can also be used
Reactors are typically made from concrete,steel and lined with lead, the combination of these materials and built into a strong shape(bullet shaped or spherical shaped etc..) make up a nuclear reactor, these materials also absorb the radiation produced inside the nuclear reactor(lead absorbs gamma radiation and concrete absorbs neutron radiation).

A shunt reactor absorbs reactive power and increases the energy efficiency of any system. It is a small device used for power compensation in high voltage transmission lines and cable systems.
Oxygen, the element with an atomic number higher by one than that of nitrogen.

A boron/steel alloy is normally used, boron is the element that absorbs neutrons strongly. Cadmium is sometimes used but I think only in small research type reactors.
As a particle absorbs the energy (heat) it begins to move and vibrate faster. This increased vibration and movement causes it to bump into surrounding particles more, passing the energy onto them. As more particles get bumped, more particles start to move in turn bumping their neighbors and conducting the energy or heat through the substance.
