Transition Metals 1a) The d-orbitals of a free transition metal atom or ion are degenerate (all have the same energy.) However‚ when transition metals form coordination complexes‚ the d-orbitals of the metal interact with the electron cloud of the ligands in such a manner that the d-orbitals become non-degenerate (not all having the same energy.) The way in which the orbitals are split into different energy levels is dependent on the geometry of the complex. Crystal field theory can be used to predict

Permission required for reproduction or display. 1 Bonding • Bonding is the joining of two atoms in a stable arrangement. • Through bonding‚ atoms attain a complete outer shell of valence electrons (stable noble gas configuration). • Atoms can form either ionic or covalent bonds to attain a complete outer shell (octet rule for second row elements)

This molecular orbital model can be used to explain why He2 molecules don’t exist. Combining a pair of helium atoms with 1s2 electron configurations would produce a molecule with a pair of electrons in both the bonding and the * antibonding molecular orbitals. The total energy of an He2 molecule would be essentially the same as the energy of a pair of isolated helium atoms‚ and there would be nothing to hold the helium atoms together to form a molecule. The fact that an He2 molecule is neither

org/oldwine/chm1045/notes/Geometry/VSEPR/Geom02.htm) Lone pairs repel more strongly than bonding pairs of electrons therefore a lone pair distorts the shape of a molecule. Nitrogen has 5 outer electrons so ammonia will have four electron pairs around the central nitrogen atom and be tetrahedral with respect to electron pairs. Ammonia‚ NH3 has a lone pair which generates more repulsion than the 3 bonding pairs of electrons. The shape of NH3 is therefore distorted tetrahedral.

To what extent is a counsellor more than just a good listener? In your discussion we would like you to draw on key elements that form the practise of counselling. In addition we would like you to consider your own qualities and skills and identify what you need to do to progress in the profession. This century has seen a rise in counselling services. We have counsellors for specific diseases‚ addictions‚ depression‚ divorce‚ name the problem and we seem to have a ‘therapist’ for it. So what
