periodic trends

What is the periodic trend in the variation of valency while going from left to right within a period? Explain your answer with reference to period 2 and 3.

What is the periodic trend in the variation of valency while going down a group? Explain your answer with reserence to the group 1, group 2 and group 18.

Specific heat of Li(s),Na(s),K(s),Rb(s) and Cs(s) at 398K are 3.57,1.23,0.756,0.363 and 0.242 J g^(-1)K^(-1) respectively. Compute the molar heat capacity of these elements and identify any periodic trend. If there is trend, use it to predict the molar heat capacity of Fr .
