Valence Electrons

Science / Geology / Valence Electrons: Electrons in the outermost shell of an atom. The electrons that are typically involved in making chemical bonds.

Valence Shell

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

Valence Electron

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

Equivalence Point

Science / Chemistry / Equivalence Point: The equivalence point is the point in a titration when enough titrant has been added to react completely with the analyte. MORE


Business / Agriculture / Equivalence: A term applied by the Uruguay Round Agreement on the Application of Sanitary and Phytosanitary (SPS) Measures. WTO Member countries shall accord acceptance to the SPS measures of other countries (even MORE

Valence Shell Electron Pair Repulsion Theory

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

Yield Equivalence

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
