Science / Geology / Valence Electrons: Electrons in the outermost shell of an atom. The electrons that are typically involved in making chemical bonds. MORE
Science / Chemistry / Valence Electron: Electrons that can be actively involved in chemical change; usually electrons in the shell with the highest value of n. For example, sodium's ground state electron configuration is 1s2 2s2 2p6 3s1; th MORE
Science / Chemistry / Valence Shell: The shell corresponding to the highest value of principal quantum number in the atom. The valence electrons in this shell are on average farther from the nucleus than other electrons; they are often d MORE
Science / Chemistry / Valence Shell Electron Pair Repulsion Theory: A model that explains the shapes of molecules by assuming that electron pairs arrange themselves around atoms in a way that minimizes electron-electron repulsions. MORE
Business / Finance / Yield Equivalence: Mainly applies to convertible securities. Graph showing the term structure of interest rates by plotting the yield of all bonds of the same quality with maturities ranging from the shortest to the lon MORE
Science / Psychiatry / Ambivalence: The coexistence of contradictory emotions, attitudes, ideas, or desires with respect to a particular person, object, or situation. Ordinarily, the ambivalence is not fully conscious and suggests psyc MORE
