Stereoisomers are molecules with the same structural formula (same number of each type of atom bonded together in the same order e.g. carbon bonded to carbon bonded to oxygen) but with the atoms arranged ...

Number of electrons from P= 5 e , Number of electrons from 3F = 3 e , Total number of electrons around P = 8 e Therefore there is a total number of 4 electron pairs surrounding P. three of which are bond ...

Energy (or enthalpy) needed to remove one electron from one atom.

A transition metal complex is a central metal ion (for example platinum) surrounded by ligands.  Ligands are ions or small molecules that donate a pair of electrons to the central metal ion and surround i...

So firstly, the first two columns in the periodic table are classed as the 's' group, the next 10 groups/columns, which are the transition metals are called the 'd' group, the last 6 colums are classified...
