Relative atomic mass average mass of an atom of an element (taking into account all of its isotopes) relative to 1/12 of the mass of a 12C atom Atomic structure exceptions Cu - 1s2 2s2 2p6 3s2 3p6 4s1 3d10 Cr - 1s2 2s2 2p6 3s2 3p6 4s1 3d5 chooses to have all 3d shell filled Hund's Rule electrons prefer to occupy orbitals on their own and only couple up when no empty orbitals of the same energy are available (since electrons paired up will cause repulsion) 4s orbital rule 4s is lo...

Name and outline the mechanism for the reaction of cyclohexane with Br2Electrophilic addition and check mark scheme Explain why there is an attraction between C=C double bond and Br2The double bond is a region of high electron density as the br molecule approach is it it becomes polarised the br positive is attracted to the double bond inducing a temporary dipole Draw the skeletal formula of the halogenoalkane formed when buta-1,3 diene reacts with an excess of Br 2 CH2=CHCH=CH...
