Morphology
The phrase is compositionally transparent: 'methylene' names the CH2 group derived from methane and 'radical' denotes a reactive species, so a learner who knows both constituents can deduce this refers to the CH2 radical. This technical naming pattern (chemical-group + radical) is regular and cross-linguistically analogous, so the meaning is predictable from the parts.
Etymology
Methylene radical names a tiny, very reactive piece of a molecule: methylene links it to methane with two hydrogens missing and radical shows it has 'open' spots that want to join other atoms. So, that image explains why the term means a short-lived, 'very reactive' particle in chemical reactions.
