If a nucleus undergoes beta particle emission
ita atomie number decreases by four and its
maas number decreases by two
ita atomie number decreases by two and its
masa number decreases by four
ita atomie number increases by one and its
mass number is unchanged.
ita atomie number decreases by one and its
maaa number is unchanged.
ita atomie number is unchanged and its mass
number decreases by one.

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
