S12F7
SF2
None of the above

I’m pretty sure it’s false i’m not sure

Particle exchange energy though elastic collision , hope this .

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
