Boron, atomic number 5, occurs naturally as two isotopes (10B and 11B) with natural abundances of 19.9% and 80.1% respectively. In what ways do the two isotopes differ? Do the electronic configurations differ? Draw the orbital diagram for 11B. Which electrons are the valence? Give three ways the 1s and 2s orbitals differ for this element. Elemental boron reacts withF2 gas to form BF3(g). Write balance equation for this reaction. If the delta Hf for BF3 is -1135.6 kJ/mol, find the standard enthaply change for the reaction. Draw the lewis structure for BF3.

***please write out on paper nice and neat!

The element technetium (atomic number 43) is radioactive and one of its isotopes, 99Tc, is used in medicine for diagnostic imaging. The isotope is usually obtained in the form of the pertechnetate anion, TcO4-, but its use sometimes requires the technetium to be in a lower oxidation state. Reduction can be carried out using Sn2+ in an acidic solution. The skeleton equation is TcO4- + Sn2+ → Tc4+ + Sn4+ (acidic solution) Balance the equation by the ion–electron method.
