the salt-makers, so desperate to bond they'll steal an electron from almost anyone.
means Any of the five chemically reactive nonmetal elements in group 17 of the periodic table — fluorine, chlorine, bromine, iodine, and astatine — known for readily forming salts when they combine with metals.
from Coined in the early 19th century by a Swedish chemist (the name is usually credited to Berzelius's circle) from Greek 'hals,' meaning salt, plus '-gen,' the suffix for 'producing' or 'born of' (from 'gennao,' to beget). So a halogen is literally a 'salt-producer' — that same 'hals' surfaces in 'halite,' the mineral name for rock salt, and the '-gen' is the very same one that powers 'oxygen' and 'hydrogen.'
