N-type - In N-type doping, phosphorus or arsenic is added to the silicon in small quantities. Phosphorus and arsenic each have five outer electrons, so they're out of place when they get into the silicon lattice. The fifth electron has nothing to bond to, so it's free to move around...
What is lattice energy? Learn the definition of lattice energy, see its trends in the Periodic Table, and study how to find lattice energy using its formula. Related to this Question Calculate the standard free energy of the following reactions at \, 25^\circ\text{C}...
Learning to start a fire in the wild without a match can be a tricky thing to do at first. Find out how to start a fire without a match in the wild.
Even after all these years, scientists still don't fully understand how gluey substances make one thing stick to another, though they've got some pretty good ideas. Let's take a closer look!Photo: Without adhesives, all kinds of everyday jobs would be much more difficult. Adhesive bandages...

You may have already guessed a couple of problems that we'll have to solve. First, what do we do when the sun isn't shining? Solving Solar Energy Issues If you worry that your solar cells won't perform on a stormy day, you can always store the sun's energy in backup batteries.nre...
we call it potential energy; "potential" simply means the energy has the ability to do something useful later on. When stored energy is being used to do something, we call it kinetic energy; "kinetic" means movement and, generally, when stored energy is being used up, it is making things...
