I am reading Kenneth W. Ford's book entitled "The Quantum World". On page 22 under the introduction section to Charge, he talks about how charges lead to pairing. In that paragraph he states... "The hydrogen atom...consists of an electron and a proton held together by electrical attraction. More energetic particles don't pair up as the result of electrical forces; they merely deviate from a straight path." Can someone please explain what Kenneth means by the statement in RED? When he talks about "more energetic particles", is talking about atoms with more mass such as such as helium, oxygen, etc. Or is he talking about other heavier fundamental particles (Muons and Tauons)?
