عندي واجب وابي أي احد عنده خبره في الكيميا يساعدني فيه
السوال هو
Boron, atomic number 5, occurs naturally as two isotopes, 10B and 11B, with natural abundances of 19.9% and 80.1%, respectively. (a) In what ways do the two isotopes differ from each other? Does the electronic configuration of 10B differ from that of 11B? (b) Draw the orbital diagram for an atom of 11B. Which electrons are the valence electrons? (c) Indicate three major ways in which the 1s electrons in boron differ from its 2s electrons. (d) Elemental boron reacts with fluorine to form BF3, a gas. Write a balanced chemical equation for the reaction of solid boron with fluorine gas. (f) When BCl3, also a gas at room temperature, comes into contact with water, the two react to form hydrochloric acid and boric acid, H3BO3, a very weak acid in water. Write a balanced net ionic equation for this reaction
