What is the orbital notation and electron configuration for the following atom or ion: a. calcium b. arsenic c. fluoride d. F- e. Mg2+ How many valence electrons occupy sigma-bond orbitals? Explore our homework questions and answers library ...
We calculated the propensity of each bond and residue (relative to the FliM-binding site) in fully activated CheY (PDB ID: 1F4V) bound to Mg2 þ , BeF3 and FliM. We identify a number of hotspot surface residues with high quantile scores (Fig. 2a), including the phosphorylation site, ...
Aqueous ammonium ion batteries are regarded as eco-friendly and sustainable energy storage systems. And applicable host for NH4+in aqueous solution is always in the process of development. On the basis of density functional theory calculations, the excellent performance of NH4+insertion in Prussian bl...
Molecular orbital study (CNDO/2) of cation charges in forsterite (.ALPHA.Mg2SiO4) Semi-empirical molecular orbital study (CNDO/2) has been performed for a large cluster of atoms (Mg(1)3Mg(2)2Si2O22H26)0+ to evaluate cation charges of forsterite. Hydrogen (H) atoms were attached to...
Molecular structure and bonding character of mono and divalent metal cations (Li+, Na+, K+, Be2+, Mg2+, and Ca2+) with substituted benzene derivatives: AIM... Cation–π complexes between several cations (Li + , Na + , K + , Be 2+ , Mg 2+ , and Ca 2+ ) and different π-sy...
SERUM MG2The tensor character of the first-order density matrix leads to the definition of an MO multicenter bond index for closed-shell systems. It is here applied to three-center bonds. Satisfactory results are obtained for compounds involving "secondary" bonds, strong and normal hydrogen bonds...
Several recent papers report spectacular, and unexpected, order of magnitude improvement in creep life of alloys upon adding small amounts of elements like zinc. This microalloying effect raises fundamental questions regarding creep deformation mechanism

The kcat and Ka values, measured for the Mg2+, Mn2+, and Ca2+ activation are listed in Table 2. Mn+2 and Mg2+ are significantly better activators for OAH than is Ca2+. The kcat values determined using the 0.1 m imidazole buffer do not differ significantly from those measured using the...
This labelling strategy enabled a detailed characterisation of the nucleotides around the scissile phosphodiester bond in the ground state conformation of the hammerhead ribozyme in the absence and presence of Mg2+ ions as well as of the product state. Photochemical induction of the reaction in situ ...
