Lone Pairs

Some articles on lone pairs, pairs, pair, lone pair:

Hydrogen Bonds in Water
... water, more bonds are possible because the oxygen of one water molecule has two lone pairs of electrons, each of which can form a hydrogen bond with a hydrogen on ... molecule is H-bonded with up to four other molecules, as shown in the figure (two through its two lone pairs, and two through its two hydrogen atoms) ... unique because its oxygen atom has two lone pairs and two hydrogen atoms, meaning that the total number of bonds of a water molecule is up to four ...
Lewis Structure - Example
... Place ion pairs ... The 14 remaining electrons should initially be placed as 7 lone pairs ... Each oxygen may take a maximum of 3 lone pairs, giving each oxygen 8 electrons including the bonding pair ...
Metal–ligand Multiple Bond - Reactivity Explained Through Ligand Hybridization
... can bond to a metal through however many lone pairs it has available ... For example many alkoxides use one of their three lone pairs to make a single bond to a metal center ... Increasing the bond order to two by involving another lone pair changes the hybridization at the oxygen to an sp2 center with an expected expansion in the M-O-R bond angle and contraction in the M-O bond ...
Lewis Structure - Construction - Counting Electrons
... They should be placed initially as lone pairs one pair of dots for each pair of electrons available ... Lone pairs should initially be placed on outer atoms (other than hydrogen) until each outer atom has eight electrons in bonding pairs and lone pairs extra lone pairs may then be placed ... When in doubt, lone pairs should be placed on more electronegative atoms first ...

    Your star, steel-set, keeps lone and frigid tryst
    to freighted ships, baffled in wind and blast.
    Hilda Doolittle (1886–1961)
