A chemist has discovered a “new" element. This element has similar properties as Nitrogen . If the ion of this new element has 200 electrons , what would be the atomic number of this new atom. Explain Please no BS answer

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

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

Idk the answer imthink snail cant mate they dont lol
