Question 10

  • Highest ionization energy: He

    The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest. Ionization Energy sciaüifictutor.org https://www.angelo.ed u/faculty/kboudrea/ htm You visited this page.

Question 15

  • Lewis acid-base reaction and coordination complex

    Metal-Ligand Bond This bond is formed between a Lewis acid and a Lewis base. The ligands (Lewis bases) have nonbonding electrons. The metal (Lewis acid) has empty orbitals. Che stry of Coordination

    The Lewis Acid-Base Concept:Coordination Compounds. In a Lewis acid-base neutralization, the base donates a pair of electrons forming a coordinate covalent bond which joins the two species together into the reaction product.
