Determining the charge of an atom is easy in most cases but not all. Atoms are held together by the electromagnetic forces between the protons in the nucleus and the electrons surrounding it, and this means that most of the time there isn't actually much to work out. But when elements lo...
When you knock an electron off of an atom, you end up with a free electron (with a negative charge) 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...
But you don't have to wait for a storm to bring an electromagnet to life. A current is introduced, either from a battery or another source of electricity, and flows through the wire. This creates a magnetic field around the coiled wire, magnetizing the metal as if it were a permanent ...
on most android phones, a screenshot can be taken by pressing the power and volume down buttons at the same time for a few seconds. after letting go of the buttons, the screenshot is taken. a specific type of shutter soundconfirms the screenshot has been taken. you can edit the screen...
When the ultraviolet light strikes atom of the phosphors (shown here as white dots), it excites their electrons in just the same way that the mercury atoms were excited. This makes the phosphor atoms unstable, so they give off their excess energy as photons—which, this time, happen to be...
Work with partners that are uniquely positioned to build a multicloud framework that leverages the best of enterprise infrastructure wherever you need it, however you choose to consume it, in a CapEx, OpEX or Hybrid financial constructs that exceeds your goals. All to reduce risk and accelerate ...
Choosing the right color for your sunglasses lets them work better in specific situations. When you buy a pair of cheap sunglasses, you often give up all of these benefits and can even make things worse. For example, if your sunglasses offer no UV protection, you increase your exposure to ...
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 ...
Delegator: A delegator is an individual who participates in The Graph protocol by delegating their Graph Tokens (GRT) to specific indexers. Delegators do not operate their own infrastructure but instead support indexers by allocating their GRT holdings to them. The different products ...
In both cases, a static charge has built up as the result of two very different materials rubbing against each other. The rubbing can knock loose electrons -- the outer, orbiting, negatively charged parts of an atom -- from some fabrics onto others. So your sweater, for example, might en...
