Document Summary
Review extra practice exercises ( 8. 1 . -8. 10; pg 337 for answers) Rutherford"s atom: what is meant by the expression nuclear atom , although rutherford"s experiments confirmed the existence of the positively charged nucleus, they left many questions about the structure of the atom unanswered. One of these is due to the n=6 to n=2 transition and the other is due to the n=5 to n=2 transition. Why: write electron configurations for each of the following transition metals: i)co ii) ni iii) cu iv) zn. Write the complete orbital diagram for each of the following elements, using boxes to represent orbitals and arrows to represent electrons. i) aluminum, z = 13; ii) phosphorous, z = 15; iii) bromine, z =35, iv)argon, z =18. 30) how many valence electrons does each of the following atoms possess? i) cs, b, ba, se. Write electron configurations for the following ions: ca2+, s2-, al3+
