What is the probable location of an electron called?

Orbitals

The orbital of an electron is the most probable location where the electrons might be found. (Orbitals are very important in biology.) Electrons can absorb or release energy and when doing so, may change energy levels. This characteristic of electrons is the way we obtain energy for life.

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
