How many electrons does cobalt have?CobaltCobalt is a transition metal that is located in the first row of the transition metals. Its atomic mass is 58.933 g/mole and is used to make blue pigments. The largest mining operations for cobalt are in Central Africa....

The positively-charged anode, a flat disc made of tungsten, draws the electrons across the tube. X-ray machines seem to do the impossible: They see straight through clothing, flesh and even metal thanks to some very cool scientific principles at work. Find out how X-ray machines see ...
Once you apply enough heat to cause white light, you are energizing so many different electrons in so many different ways that all of the colors are being generated -- they all mix together to look white. Heat is the most common way we see light being generated -- a normal 75-watt ...
So we get a kind of chain reaction in which even a single particle of radiation can produce avalanches of electrons in rapid succession; this process is known as a Geiger discharge. Many electrons travel down the wire making a burst of current in a circuit connected to it. The electrons ...
Does light travel as a wave, a ray or a stream of particles? Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think ...
Tungsten k-shell electrons have a binding energy of 69.5keV, so to kick these out your impacting electrons must have energies greater than 69.5keV. Typically one would need to give the anode a bit more than 72kV to accomplish this, hence the standard 75kV x-ray tube. ...
electrons, or six electrons in its outermost orbital. You can also figure out how many electrons are in its first, second and third orbitals: The first orbital can hold a maximum of two electrons, while the second has four suborbitals and so can hold a total of eight electrons. The third...
How Does a Microscope Work? - ElectronAs previously mentioned, optical microscopes are limited in resolution by the frequency of the light waves. Electron guns emit a flow of electrons of a considerably shorter wave length than visible light and this fact allows an electron microscope to have ...
