Discovering Atomos 4
| Question | Answer |
|---|---|
| electron configuration | the organization of electrons around the nucleus of an atom, determined by the number of electrons an element possesses and their position in the energy levels around the atom |
| electron cloud | a region around the nucleus in which electrons are predicted to be found at any given point, sometimes represented as orbitals or energy levels; used to approximate the location and behavior of electrons |
| energy levels | a region surrounding the nucleus of an atom; the location and behavior or electrons can be predicted based on these |
| orbitals | another name for energy level; a field that defines the pattern and position in which electrons move about the nucleus of an atom |
| 1st orbital | can hold only two electrons |
| 2nd orbital | can hold only eight electrons |
| valence electrons | an electron found in the outermost (usually incompletely-filled) orbital of an atom; determine how an element combines with other elements |
| 3rd orbital | can hold up to eighteen electrons |
| eight | elements are the most stable when they have ________ electrons in their outermost orbital |
