When the nucleus boron-10 is bombarded with neutrons it absorbs a neutron and then emits an alpha particle How many protons does the resulting nucleus have?

If boron-10 absorbs a neutron, it becomes boron-11. Boron-11 is stable and does not emit any particles. Please restate the question.

What will an alpha particle change into when it absorbs two electrons?
When it captures (not absorbs) electrons and becomes neutral the alpha particle becomes a helium atom.
What types of rods slow down nuclear reactions?
Control rods that absorb neutrons. These contain some material that strongly absorbs neutrons, boron is most often used but cadmium has similar properties.
What is a fission nuclear reaction?
The primary result of a fission reaction is the conversion of mass to energy. In fission, the nucleus split, either through radioactive decay or as result of being bombarded by other subatomic particles known as neutrons.
Control rods are used in a reactor core to?
Reactor control rods are made of a substance that absorbs neutrons.
How is energy passed from particle to particle during heat conduction?
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.
What will an alpha particle change into when it absorbs two electrons?
When it captures (not absorbs) electrons and becomes neutral the alpha particle becomes a helium atom.
Boron-10 is used as control rods in nuclear reactors it absorbs a neutron while it emits an alpha particle what is the resulting product in the control rods?
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.
Is uranium-235 an alpha particle?
No. 92235U is a radioisotope with 92 protons, 143 neutrons, and (in a non-ionic, neutral state) 92 electrons. An alpha particle, on the other hand, is a helium nucleus, 24He2+ with 2 protons, 2 neutrons, and no electrons. It happens that 92235U decays by alpha decay to 90231Th with a half-life of 7.04 x 109 years, but this does not means that it is an alpha particle, it means that it emits an alpha particle. It also decays by spontaneous fission with a probability of 7 x 10-9%. It primary value, however, is that it is fissile, meaning that if it absorbs a thermal neutron, it will undergo fission, generating more neutrons, two new isotopes, and energy.
How to control nuclear reactions?
With control rods made of Cadmium metal, which absorbs neutrons.
What absorbs neutrons in a nuclear reactor and begins with C?
We see the use of control rods in a reactor to absorb neutrons. These rods are often made of boron.
What is absortption?
Absorption is the action or process by which one thing is absorbed by or absorbs another thing. Or it could also mean: the action or process by which the nucleus absorbs neutrons.
What will an alpha particle change into when it absorbs one electron?
it changes to single ionized helium ion
What element is produced when nitrogen 14 is bombarded with an alpha particle and a positron is emitted?
In the reaction where nitrogen-14 absorbs an alpha particle, we see the formation of oxygen-17 and a proton. Here's how it looks: 714N + 24He => 11P + 817O Note that the alpha particle is written the way it is because we know that an alpha particle is a helium-4 nucleus. Simple and easy. The equation is balanced, and you can observe that by adding the subscript and the superscript numerals on one side and checking them against those on the other side. In this case, 7 + 2 = 1 + 8, and 14 + 4 = 1 + 17.
What is an absorber?
An absorber is a device which allows gas or vapour to be absorbed by a liquid, a person who absorbs, or a material which absorbs neutrons in a reactor.
What is a radioactive atoms?
A radioactive atom is an atom that has an unstable nuclear force, and therefore either absorbs or emits a radioactive particle.
What types of rods slow down nuclear reactions?
Control rods that absorb neutrons. These contain some material that strongly absorbs neutrons, boron is most often used but cadmium has similar properties.
What element absorbs neutrons and is used to make control rods for nuclear reactors?
Boron is the most commonly used, cadmium can also be used
