The Big Secret of Atoms For many years, the little atom kept a big secret. Men were sure the atom could be put to work. But they didn't know how. They knew that some atoms never change. But some atoms fly away. About twenty-five years ago, men l

The basic rule is that the tools you use have to be smaller than the things you're using them on.Photo: Inside an atom: electrons are the particles in shells (orbitals) around the nucleus (center).And the same goes for science. The smallest thing you can see with a microscope is ...
Those wishing to see the northern lights will also be happy to hear that while aurora activity is high during solar maximum it actually peaks a couple of years after solar maximum. So the best northern lights are yet to come! Experts say the 2026-2027 aurora season is the big one so mar...
Similar to non-ionizing radiation, ionizing radiation is energy in the form of particles or waves. However, ionizing radiation is so high in energy it can break chemical bonds -- meaning it can charge (or ionize) an atom that interacts with it. At a lower energy, it may strip off a co...
and an atom missing one electron (with a positive charge). The negative electron is attracted to the plate with a positive voltage, and the positive atom is attracted to the plate with a negative voltage (opposites attract, just like with magnets). The electronics in the smoke detector sense...
Obviously, lack of water is a big problem. But why is that, exactly? In the next section, we'll look at the part that water plays in the human body. Conserving Water One way you can help reduce the demand for water is to conserve water year-round. Many areas ban watering your...

atom, it knocks loose an electron in one of the atom's lower orbitals. An electron in a higher orbital immediately falls to the lower energy level, releasing its extra energy in the form of a photon. It's a big drop, so the photon has a high energy level -- it is an X-ray ...
