Review 4 ESO L1 and L2

• Take the elements A)Z=12; B)Z=17 and C)Z=36. Write their electrónic configuration, their Group and period. Tell their aggregation state, their stable iones.  Order them by their increasing atómic radious, electronegativity, ionization potential. For the bonds A-A, B-B, A-B, Tell which Will be gaseous, which Will be a solid electrical conductor and which will be an electric conductor. 

• Summarise the 4 atomic models: author, experiment and what it consists of. 

• When we measure the kinetic energy against the speed, we get these data:

        v(m/s) 2; 4;  5;  6
        E (J) 8; 32; 50; 72
     Graph these data, determine the type of relationship and the equation E as a function of v.
