Using the periodic table: 3 and 3 Bilingual

When we locate an element in the periodic table, we inmediately know: 

1. Its atomic number
2. Its electronic configuration 

   

   fig 1: Periodic table trends

3. Its period and family
4. Its relative size
5. Its metallic character
6. Its relative electronegativity
7. The bondings with other elements: If the two are on the left side of the periodic table (except H): Metallic; If one is on the left and the other is on the rigth: ionic; If the two are on the rigth: covalent.

If we look at table position´s to find K and Cl (find them), we will see:

K Z=19; It is a metal: period 4, group I, [Àr] 4s1, alcali metal,
F Z=9; It is non metal. Halogen. [Ne] 3s2 3p5

We can order their properties by their  position: a) Atomic radius: K is on the left and in a bigger period: look at the trend in fig 1: K atom is much bigger than Cl; K is also much more metallic. The ionization energy is bigger for Cl, because it is on the rigth and in a lower period.
They will form an ionic bonding: a Crystal.

In the table, locate these elements: Rb, Ca, P, and O and:
a) Tell their atomic number, period, group, and if it is a metal; (3 ESO: electronic configuration)
b) Order them by its atomic radious, metallic character, ionization energy
c) (3 ESO): Tell the kind of bonding between: Rb and O; Ca and Ca, P and P
