Boron is the most commonly used, cadmium can also be used
One or more elements that strongly absorb neutrons, some are:cadmiumboronhafniumetc.
neutrons
No but element number six on the periodic table has 6 protons 6 neutrons and 6 electrons. Melanin appears black because it absorbs energy and doesnt reflect it back.
The element that has 8 protons and 8 neutrons is oxygen.
about 66 or 64

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.
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.
Hafnium can be used as a material for control rods in nuclear reactors. This element has a high neutron absorption cross section, and it appears as a big target for neurtons.

There are 118 neutrons in the element gold.
there are 61 neutrons in a the element silver
