Q:

What happens when you split an atom?

A:

Also referred to as nuclear fission, splitting an atom results in its overall mass being reduced, causing the release of a relatively massive amount of energy. Virtually every atom can generate nuclear energy in this way, but those with the greatest atomic mass will provide the most energy from fission.

Nuclear reactors rely on fission to generate heat, which then causes cooling pools to boil, driving steam turbines. In other cases, it is the sudden and violent fission process that results in nuclear detonations that can devastate huge geographic areas. The process itself is remarkably efficient, but requires a large investment of initial energy to generate. In opposition to fission, the fusion process by which two atoms are joined generates several times as much energy, but does not present the risk of nuclear contamination or pollution. As well, spent isotope fuel rods remain hazardous for many thousands of years while the materials consumed during the fusion process remain safe to handle and transport. The most common fusion process, that of converting hydrogen and oxygen into water, is often the easiest and most frequently referred to. Not only are these two elements the most plentiful, they also join more readily than other elements.

  • Q:

    What is nuclear fission?

    A:

    According to the International Atomic Energy Agency, nuclear fission is the process by which large, heavy atoms split into lighter ones, releasing substantial amounts of energy in the process. This can occur due to natural radioactive decay, or it can be triggered by an atomic collision. Nuclear fission can power reactors or create massive explosions if uncontrolled.

    What are the main events of anaphase?

    A:

    The main events of the anaphase stage of mitosis are the splitting of the sister chromatids and the moving of them to opposite poles inside the cell. The process begins when the centromeres on each chromosome break, freeing the two halves.

    What are angiotensin II receptor blockers?

    A:

    Angiotensin II receptor blockers are medications that inhibit the release of a hormone that increases the amount of sodium and water in the body, causing a rise in blood pressure. This hormone also narrows and stiffens the walls of the blood vessels and heart. Angiotensin II receptor blockers, which are sold under various trade names, alleviate hypertension by allowing blood vessels to dilate, according to the Mayo Clinic.
