Q: What term did schrodinger use for regions around the nucleus where electrons are most likely to be? Read this paragraph and choose the correct option from the provided answers: Schrodinger developed an equation that could be used to calculate the chances of an electron being in any given place around the nucleus. Based on his calculations, he identified regions around the nucleus where electrons are most likely to be. He called these regions orbitals . As you can see in the Figure below , orbitals may be shaped like spheres, dumbbells, or rings. In each case, the nucleus of the atom is at the center of the orbital. You can see animated models of orbitals this URL: http://www. chemistry. wustl. edu/~edudev/Orbitals/movie. html . Choices: - arrays - isotopes - ellipses - orbitals A:
**Answer**
orbitals

Q: An example of a variable relating to the ramp is its what? Read this paragraph and choose the correct option from the provided answers: A: Variables might include factors relating to the ramp or to the object. An example of a variable relating to the ramp is its steepness. An example of a variable relating to the object is the way it movesit might roll or slide down the ramp. Either of these variables could be manipulated by the researcher, so you could choose one of them for your manipulated variable. Choices: - color - mass - weight - steepness A:
**Answer**
steepness

Q: Light retains its original color under water because what remains the same when light is refracted? Read this paragraph and choose the correct option from the provided answers: When light is refracted its wavelength and speed change; however, its frequency remains the same as the frequency of the light source. Proof of this is that light retains its original color under water. For example, blue light is still blue under water. Choices: - wave length - density - sound - frequency A:
**Answer**
frequency
