aayan

aayan (ion) aise parmaanu ya anu hai jismein ilektraanon aur protonon ki sankhya asaamaan hoti hai. is se aayan mein vidyut aavesh (chaarj) hota hai. agar ilektraun ki taadaad proton se adhik ho to aayan mein rinaatmak (negetiv) aavesh hota hai aur use rinaayan (anion, ainaayan) bhi kehte hain. iske vipreet agar ilektraun ki taadaad proton se kam ho to aayan mein dhanaatmak (pojitiv) aavesh hota hai aur use dhanaayan (cation, kaitaayan) bhi kehte hain.[1]

rinaayan aur dhanaayan

ek ilektraun aur ek proton mein baraabar ka vidyut aavesh (chaarj) hota hai. isaliye kisi aayan ka avesh usamein maujood protonon ki sankhya ko usamein maujood ilektraunon se ghataakar bataaya jaata hai. agar protonon ki sankhya adhik ho to yeh aavesh dhanaatmak (pojitiv) hota hai aur agar ilektraunon ki sankhya adhik ho to yeh aavesh rinaatmak (negetiv) hota hai.

  • rinaayan (−): inmein ilektraun adhik aur proton kam hote hain. angreji mein inhein kaitaayan (cation) kehte hain kyonki dhanaatmak aavesh vaale yeh aayon agar kisi vidyut kshetr mein daale jaaeain to rinaatmak (nigetiv) aavesh vaale kaithod ki or aakarshit hote hain.
  • dhanaayan (+): inmein proton adhik aur ilektraun kam hote hain. angreji mein inhein ainaayan (anion) kehte hain kyonki dhanaatmak aavesh vaale yeh aayon agar kisi vidyut kshetr mein daale jaaeain to dhanaatmak (pojitiv) aavesh vaale ainod ki or aakarshit hote hain.
