Arrange the following atoms in order of increasing effective nuclear charge experienced by the electrons in the n=3 electron shell: k, mg, p, rh, and ti. explain the basis for your order.

 I think that the effective nuclear charge increases as you go up a group and across a period. 

so maybe Rh, K, Ti, Mg, P 

 I hope I helped :)

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
