3 syllables: fer, mi, um. Stress on fer.
FER-mee-uhm
/ˈfɛɹmiəm/
fermium is pronounced FER-mee-uhm (/ˈfɛɹmiəm/). It has three syllables (fer-mi-um), with the stress on "fer". Fermium is a synthetic, highly radioactive element with the symbol Fm and atomic number 100. In scientific contexts, it is discussed as part of actinide chemistry and nuclear science. The word is used primarily in technical discourse and academic writing about radioactive materials and their properties.

"The isolation of fermium required advanced radiochemical techniques."
"Researchers at the lab discussed fermium's short half-life and decay products."
"Fermium was first created by bombarding lighter elements with neutrons."
Pronounce it as FER-mee-əm, with the primary stress on the first syllable. In IPA for US/UK/AU, /ˈfɜːrmiəm/. Start with a mid-back rhotic vowel /ɜː/ followed by /r/ then /m/; the second syllable features a clear /i/ as in 'see', and ends with a schwa /ə/ before m. Visualize saying ‘fer’ quickly, then ‘mee,’ then a soft, almost unaccented ‘um’ at the end. For audio references, you can compare to standard dictionaries’ audio clips, such as Cambridge or Oxford online dictionaries, which align with /ˈfɜːr.mi.əm/ across major variants.
Common errors include misplacing stress (say-ing fi-ERM-ium) and mispronouncing the middle vowel as a pure /i/ or confusing the final -ium with a long /iː/ or /iə/. Correct form is /ˈfɜːr.mi.əm/, with the first syllable stressed, a lax but rounded /ɜː/ plus /r/, then /mi/ with a clear /i/, and a light /əm/ ending. Practice by isolating each segment: FER (/ˈfɜːr/), MEE (/mi/), and UM (/əm/).
Across US, UK, and AU, the main variation is vowel quality in the first syllable: US/UK/AU share /ˈfɜːrmiəm/, with a rhotic /r/ in US. In non-rhotic UK variants you may hear a weaker rhotic or a non-pronounced /r/ in some positions, but typically UK still uses /ˈfɜːmi.əm/. Australian English generally mirrors UK vowels but with slightly more centralized /ɜː/ and a lighter /r/ in some dialects. Overall, the rhyme and syllables remain the same; difference lies mainly in rhotic articulation and vowel height quality.
The difficulty comes from the two consecutive vowel sounds in the middle and the unstressed, schwa-like final syllable. The /ˈfɜːr/ cluster requires a rounded, mid-central quality before /r/, which is tricky for non-rhotic speakers. The sequence /mi.əm/ can blur into /miːm/ or /miəm/ if the final syllable isn’t clearly reduced. Focus on keeping a crisp /i/ vowel before the soft, neutral /əm/; practice with slow repetition and then increase speed.
A key unique feature is the clear, two-consonant onset in the first syllable /fɜːr/. The /r/ is not silent in rhotic variants, and the /ə/ in the final syllable is reduced to a soft schwa, not an overt vowel, which distinguishes it from some very similar metallic names. Maintaining the distinction between /ɜːr/ and /ɜː/ is crucial; also, ensure the final /əm/ is short and light rather than a heavy syllable.

Fermium traces its name to the element fermium, which itself was named in honor of Enrico Fermi, a pioneering physicist in nuclear physics. The symbol Fm reflects its designation as element 100. The naming followed the convention of honoring scientists who contributed to the field; fermium was discovered in 1952 by Albert Ghiorso and colleagues at the University of California, Berkeley, during investigations of the debris from the atomic bomb tests and the neutron irradiation of plutonium-239. The root idea is the addition of the -ium suffix typical to elements, signaling a metallic, elemental substance. The term’s linguistic lineage aligns with the broader European tradition of using Latinized roots and the familiar element-naming morphology that emerged in the 19th and 20th centuries, combining a homage to Fermi with the standard atomic-naming convention. Over time, fermium has entered scientific literature as a concrete term identifying a specific, artificially produced actinide with extremely limited natural occurrence, high radioactivity, and a short half-life. The first known use in print appears in mid-20th-century nuclear chemistry and physics texts, reflecting its place in the early era of transuranic element research.
