How do we turn that into something much more useful, namely electricity? A nuclear power plant works pretty much like a conventional power plant, but it produces heat energy from atoms rather than by burning coa
How is a new substance produced when a molecule is formed? Is a new substance produced because a chemical bond or covalent bond has formed, which is what makes it a new substance?� Describe a covalent bond. What happens when two atoms form a chemical bond?
When these photons strike a metal surface, they act like billiard balls, transferring their energy to electrons, which become dislodged from their "parent" atoms. Once freed, the electrons move along the metal or get ejected from the surface. The particle theory of light had returned -- with...
The pressure is high enough to force atoms of hydrogen to come together in nuclear fusion reactions — something we try to emulate here on Earth. Two atoms of hydrogen are combined to create helium-4 and energy in several steps: Two protons combine to form a deuterium atom (hydrogen atom ...
The researchers at Antora Energy are developing a new type of thermal storage. It’s ararely used approachthat retains energy in the form of extreme heat or cold in a variety of substances, like underground rocks or ice blocks. In Antora’s case, the substance inside the tank...
A diamond is an amazing miracle of nature made up of billions of carbon atoms. Diamonds have a unique cubic crystal lattice structure. Each carbon atom in a diamond is strongly bonded to four others, making them the hardest known natural substance. Diamonds also exhibit high thermal conductivity...
Fly agaric, or Amanita muscaria, is what many people think of when magic mushrooms come to mind. These mushrooms have bright red caps with white spots and contain a psychotropic substance called muscimol. They're also toxic when raw. In some countries, including Japan and Russia, they are ...
First, water molecules (two atoms of hydrogen and one atom of oxygen joined together) naturally stick to one another, so they clump together in big droplets on the window. The forces that make them do this are called cohesive forces (and the process involved is called cohesion). Second, ...
How do you calculate the coordination number of complex compounds? How is an anion formed? Why can carbon form so many compounds? In what form do most ionic compounds occur? Which substance is a combination of different atoms? What are the visual differences between elements, compounds and mixt...
A single cell depends upon the process of diffusion to get materials across its membrane and move materials within it. Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. You can smell an onion cut in the kitchen in another room becau...
