Answer the following question given this paragraph: 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 . Q: What term did schrodinger use for regions around the nucleus where electrons are most likely to be? Choices: - arrays - isotopes - ellipses - orbitals A:
A:
orbitals
