WebChronic human exposure to high levels of chromium (VI) by inhalation or oral exposure may produce effects on the liver, kidney, gastrointestinal and immune systems, and possibly the blood. (1,4,5) Rat studies have shown that, following inhalation exposure, the lung and kidney have the highest tissue levels of chromium. (1,4,5)
WebThe difference in energy levels between 4s and 3d is small enough for the next two electrons to enter the 4s, because the electron-electron repulsion they feel if they enter 3d is enough to knock them into the 4s. ...
