Morphology
tetrafluoroethylene = fluoroethylene (opaque) = tetra + fluoro + ethylene
The final operation is adding the numeric chemical prefix 'tetra-' to a technical base; the term uses specialized chemical combining forms unfamiliar to average B1 learners, so the meaning is not readily derivable.
Etymology
Tetrafluoroethylene breaks into three parts: tetra- 'four', fluoro- from fluorine, the element behind 'fluoride' in toothpaste, and -ethylene 'a simple two-carbon gas'. So the name really means 'ethylene with four fluorine atoms', which explains why this gas is used to make plastics like Teflon that resist heat and chemicals.
