Recorded sources
7 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that electron affinity increases across a period?

Yes. Multiple reference and textbook sources state that electron affinity increases across a period from left to right, with one noting the trend holds prior to group 18. A couple of sources discuss the orbital-filling rationale or the neon exception without stating the trend outright.
