Hey , why is the electrolysis of water considered as catalysis?

is pyrolisis there in syllabus?

By what chemical process is the impurity present in iron, removed in steel making?

Please someone remove whoeven

Are radioactive elements to be excluded when they ask for ip,ea,en etc

Could someone please verify this?
1)Electrolysis of dilute NaCl solution.
At cathode: H+ ions discharged.
At anode: OH- ions discharged.
2)Electrolysis of concentrated NaCl solution.
At cathode:H+ ions discharged.
At anode: Cl- ions discharged.
3) Largest atomic radius in group 1- Francium. Group 2- Radium.
4) Most reactive element/highest electropositivity/least EA/ least IP/ most metallic character in group 1- cesium (not Francium) and in group 2-strontium (not radium).
Thank you!

I have a doubt, might be silly! :
Ions are atoms which have a net charge on them. It means that they have gained/lost electrons to achieve a stable electronic configuration. Now, they are stable. Then, why do they again gain/lose electrons to form a neutral atom?. Reply ASAP.
