atom has two electrons in its outermost shell. by losing two electrons from its m shell its l shell becomes the outermost shell that has a stable octet . the nucleus of this magnesium atom still has twelve protons but the number of electrons has decreased to ten. so, a net positive ...
Structure of Dihydrogen The dihydrogen molecule features a single covalent bond between the two hydrogen atoms that constitute it. This molecule has a linear shape and is nonpolar in nature. Each hydrogen atom contributes one electron toward the covalent bond. Therefore, the duet configuration requirem...
With the advent of electrospray ionisation (ESI) and matrix-assisted laser desorption ionisation (MALDI), mass spectrometry (MS) is now routinely used to establish the molecular formulae of gold nanoclusters (AuNCs). ESI-MS has been used to monitor the s
triphenylphosphine because of its lone pair, the 'P' atom, participates in resonance with the third phenyl ring's electron. As a result, the lone pair on the phosphorus atom is less available for donation to the species that lack electrons. Thus, triphenylphosphine functions as a weak base. ...
