Calculate the speed (in m/s) and radial acceleration (in m/s2) for a ground-state electron in the hydrogen atom. Do the same for the He ion and the Li ion. (Enter the magnitudes.)

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

Neither model is able to show the reactivity of potassium.
