The correct words are HERO, TRIP, and SEAS.The letters of the words in the group can be split into two distinct elements. Furthermore, the two elements are one proton apart from each other.
INNS = Sn + In
SAGE = As + Ge
COIN = Co + Ni
SORE = Os + Re
TICS = Sc + Ti
RANT = Rn + At
SAIL = Si + Al
BETS = Sb + Te
LACE = La + Ce
TERM = Er + Tm
MUSE = Sm + Eu
CHAT = Ac + Th
BILE = Li + Be
PATH = Th + Pa
HERO = Ho + Er
TRIP = Ir + Pt
SEAS = Se + As
From the hint:
SIP = Si + P
PUN = U + Np
