    2020-12-30 · There’s new research about hydraulic fracturing, or fracking, the process that injects water, sand, and chemicals into rock at high pressure to extract oil and gas. A new study from Harvard shows that radiation downwind of drilling sites can be significantly higher than normal—and that poses a potential health risk to nearby residents.

    The first ionization energy is the energy change for removal of the outermost electron from a gaseous atom to form a + 1 ion. In general, in the case of the main group elements, ionization energy decreases moving down in the periodic table and increases going across, although there are several exceptions.

    is short for hydraulic fracturing. It's a water-intensive process where millions of gallons of fluid — a mix of water, sand, and chemicals— are injected underground at high pressure to fracture the rock surrounding an oil or gas well. This releases extra oil and gas from the rock, so it can flow into the well.
