No, I don't think we have my name is li Xiao, my name is Fred Smith. Jimmy practice medicine hi, miss Watson a pleasure to meet you. Jack she is from England. Yes, I think we have met before. It's good to see you again. That's right. Mister li. Mister Fred Miller. Our ma...
What bond is formed when electrons are shared between atoms? When two hydrogen atoms chemically bond to one oxygen atom, what do they create? What is a group of atoms joined together called? Chemical bonding is the combining of atoms to form what?
The arrangement of atoms within a molecule is called the molecular structure. The molecular structure varies depending upon which atoms are in the...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer your ...
Which of the bonds in the dipeptide below is a peptide bond? How do the two strands of DNA come together to give the double helix structure? What kind of intermolecular force is involved in this part of the molecule? I...
There is also such a thing asantimatter, which is not the same as dark matter. Antimatter consists of particles that are essentially the same as visible matter particles but with opposite electrical charges. These particles are called antiprotons and positrons (or antielectrons). When antiparticl...
The universe has the critical density if it contains, on average, six hydrogen atoms per cubic meter. But matter is not spread evenly throughout the universe. We know this because we see it concentrated within galaxies and absent in the gaps between galaxies. However, when we talk about the...
An N-type semiconductor is one that carries current in the form of negatively-charged electrons. This is very similar to conduction of current in a wire. A P-type semiconductor is one that carries current predominantly as electron deficiencies called holes. A hole has a positive electric charge...
It can also occur at a molecular level, due to changes in the orientation of electrically polar molecules in response to an applied field, or through bending & stretching of the bonds between atoms within a molecule, very much like the material in a mechanical spring is bent or stretched. ...
It would be the harbinger of an entirely new medium of calculation, borrowing subatomic interactions to solve incalculable problems. Your part in making it happen may begin with convincing yourself black is white and up is down.
Atoms are the basis of the elements. There are 118 known elements in the Periodic Table, 92 of which occur naturally, and each is based on a different atom. The word "atom" comes from the Greek "atomos", meaning something that is uncuttable, or which cannot be split. Once upon a tim...
