Periodicity


 * Periodic Trends**

Compare (and account for) the trends across Period 2 and Period 3 with respective to the following properties: 1. Melting point - across Periods 2&3;  2. Metallic character – to also look into (a) type of ions formed; (b) type of oxides formed [across Periods 2&3]  3. Metallic character - down Groups 4, 1&7.  4. Atomic radius - across a Period and down a Group  5. Ionization Energy - across a Period and down a Group  6. Electronegativity - across a Period and down a Group
