(Tin and lead can also form molecular compounds in which all four valence electrons are involved in covalent bonding.) Elements from the d-block form 2+, 3+, or, in a few cases, 1+ or 4+ cations. Many d-block elements form two ions of different charges. For example, copper form...

which depends on molecular geometry given by the atoms’ space locations. Potential energy calculations are based on mechanics developed by classical physics. An illustrative model where atoms can be represented as balls and bonding as springs connecting the balls can represent this approach. Atomic in...
cleaning the surface of concrete and the uncovered reinforcement, supplementation of significant reinforcement losses, application of a bonding layer (in some systems preceded by application of corrosion inhibitors on rebars), filling of deep losses, filling of shallow losses (patching), and (not alway...
My organic chemistry textbook briefly mentioned that, in aprotic (non-hydrogen bonding) systems, the nucleophilicity trend is "often" reversed. Here the smaller nucleophile does not get the same potential energy decrease that H-bonding affords it, and the concentrated charge makes it more reactive....
