In 16th group of modern periodic table , although oxygen is in 1st period why it has the least electron affinity?

That's because the size of oxygen is smaller than that of sulphur.Hence as the size is less there exists electron repulsion within oxygen atom if you add an extra electron , hence less electron affinity that is its difficult to add an extra electron .

Wrong dude, that is applicable for 14,15,17 group only.
Our teacher taught like this bro , its like how chlorine and fluorine differ from each other in electron affinity same way here also
Nope I am 100℅ sure .u r misguided plz clear it.

Nah! Elements of 3rd period have higher EA then 2nd period

⭐⭐⭐ Hey mate!!⭐⭐⭐
__________________________________________________________
Since,
⚡❄️EA of oxygen is -141kj
⚡❄️And that of sulphur is -200kj
⚡(-ve sign becoz it is exothermic)
So,
⚡⚡Its, a value based question....
