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.

What is the reaction of passing Chlorine through AgNO3 solution?

is promoter of contact process is there in syllabus

1)Why shud a deliquescent alkali not be used for the preparation of ammonia?

3)How does decreasing the pressure help in concentration of HNO3?
4)Which alloy is used to make magnets and what is its composition?
5)Is pig iron an alloy or just incompletely purified iron which is converted to steel.Give reason.
