WebJust as wood is easier to split with the grain than against it, gemstone cleavage is the tendency of certain crystals to break along definite plane surfaces. If there are planes in a crystal structure with relatively weak atomic bonds, the crystal is more likely to break along those planes. Green fluorite with prominent cleavage.

What is Gemstone Cleavage? - International Gem Society
WebNov 24, 2014 · What is bond cleavage? Bond cleavage is the splitting of a chemical bond. There are two types of bond cleavage: homolytic and heterolytic. In homolytic cleavage, the two electrons in the bond are divided equally between the products. In heterolytic cleavage, one atom gets both of the shared electrons. Ernest Z. · 5 · Dec 11 2014 Questions WebThe most common reaction of ethers is cleavage of the C–O bond by strong acids. This may occur by S N 1 or E1 mechanisms for 3º-alkyl groups or by an S N 2 mechanism for 1º-alkyl groups. Some examples are shown in the following diagram. The conjugate acid of the ether is an intermediate in all these reactions, just as conjugate acids were ... WebIn nucleic acid: Cleavage Following synthesis by transcription, most RNA molecules are processed before reaching their final form. Many rRNA molecules are cleaved from much larger transcripts and may also be methylated or enzymatically modified. In addition, tRNAs are usually formed as longer precursor molecules that are cleaved… Read More black panther track pants india
