Pentaatomic Planar Tetracoordinate Silicon with 14 Valence Electrons: A Large-Scale Global Search of SiX(n)Y(m)(q) (n + m = 4; q= 0, ±1, -2; X, Y = Main Group Elements from H to Br). J. Comput. Chem. 2015, 36, 355-360....
Valence bond theory describes a covalent bond as the overlap of half-filled atomic orbitals (each containing a single electron) that yield a pair of electrons shared between the two bonded atoms. We say that orbitals on two different atoms overlap when a portion of one orbital and a portion ...
c) a lone pair, a single bond, a double bond, a triple bond and a single electron - each of these is counted as a single electron group. d) bond angles may depart from the idealized angles because lone pairs of electrons take up less space than bond pairs. ...

(a) (i) Number of valence electrons of the elements present in a group do not change. (ii) The elements present in the same period have same number of shells. (b) (i) The number of shells of elements in a group gradually increase downwards. (ii) Th
Although six-coordinated transition metal complexes with octahedral structures are expected to follow the 18-electron transition metal rule28, protonation of the carbyne carbon of osmapentalyne results in an aromatic osmapentalene having an osmium with only 16 electrons. Could the magnitude of the Mo...
