What element is used in microwave equipment?

The element that is used in microwave equipment is no other that Gallium. Gallium is a chemical element with a chemical symbol ga and its atomic number is 31. There are many uses of Gallium, Gallium arsenide is used in semiconductor production mainly for laser diodes, light-emitting diodes and solar panels.

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
