A conductor is a material through which electricity -- a flow of electrons -- easily moves. The entire copper core is coated with an even layer of phosphor lubricant. Phosphor -- like the kind in light sticks and other glow-in-the-dark products -- is the key to electroluminescent wire....
Worldwide, hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power. The world's hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National Renewable...
You can determine the strength of a magnetic force by adjusting the current flowing through the electromagnet. Superconducting magnets are a type of electromagnet that use the phenomenon of superconductivity to produce a highly strong and persistent magnetic field. It consists of coils made of ...
located closer to the nucleus, while valence electrons are the furthest away. These valence electrons are available for covalent or ionic bonding (through a redox reaction) with other atoms. You can determine the number of core and valence electrons from the atom's position in the periodic ...
It would resemble our regular atoms -- a positively charged core made of quarks, with electrons around -- only heavier. Frequently Asked Questions What would happen if strange matter met a black hole? If strange matter, which is incredibly dense and stable, were to encounter a black hole, ...
Of the following elements, which would you expect to have the lowest ionization energy? Which would have the highest? K, F, Mg Step 1:Determine the effective nuclear charge for each element. Potassium has 19 protons and 18 core electrons, so the effective nuclear charge is...
In the dark, the photoconductive layer on the drum acts as an insulator, resisting the flow of electrons from one atom to another. But when the layer is hit by light, the energy of the photons liberates electrons and allows current to pass through! These newly freed electrons are what ...
Approximately 30 years later, a French scientist by the name of Charles Augustin de Coulomb conducted several experiments to determine the variables affecting an electrical force. His work resulted in Coulomb's law, which states that like charges repel and opposite charges attract, with a force ...
Find the atomic number of the element to determine the number of electrons on its outer shell. For example, the Potassium (K) element has an atomic number of 19. Therefore, it will have one electron on its outer shell because it has two electrons in its inner-most shell, eight on its...
During this reaction, the reddish-orange dichromate ion changes color to the green chromium ion when it reacts with the alcohol; the degree of the color change is directly related to the level of alcohol in the expelled air. To determine the amount of alcohol in that air, the reacted mixt...
