The nucleus comes from a Greek word that means unable to be what?

Answer 1

}Nucleus = Unable to be split.

The original Greek word is ΑΤΟΜΟΝ ( = Α + ΤΕΜΝΕΙΝ (verb) ) standing for: Undissectible*, or: Indissectible* (In-dissectible).

*I think both those words are not used in English.

Nucleus = Non clust-able (non-clausable).

Though "Nucleus" is in its Latin form, being a Latin word, the original Greek word would be: ΝΗΚΛΩΣΤΟΝ or ΝΗΚΛΑΥΣΤΟΝ or ΝΗΘΡΑΥΣΤΟΝ or ΝΑΘΡΑΥΣΤΟΝ*, standing for: Unable to be broken down, unable to be split, break-proof.

* This word is used in modern Greek in a different form: ΑΘΡΑΥΣΤΟΝ, meaning: Break-proof.}

Uhhhhh..... no.The term "nucleus" is neither of Greek origin, nor does it mean "undissectable". The information on the term "atom" given above is essentially correct - it *is* Greek, and *does* effectively mean "indivisible" ; where it errs is in the assumption that there exists any derivational relationship between it and "nucleus, (cf. above: "The original Greek word..."). No links, either in definition or etymology, exist between the two. Moreover, their meanings as scientific terms aren't equivalent, though a relationship there does indeed exist. In very broad and liberal associational strokes, "nucleus" is to "atom" as "engine" is to "car". "Nucleus" is, in fact, of direct Latin lineage. It is the diminutive form of the word "nux", which is Latin for "nut" or "kernel". When Ernest Rutherford's research on atomic structure produced evidence that refuted J.J. Thompson's "plum pudding" structural model, he named the dense inner core of the atom "nucleus" because his own supplanting structural model evoked a fruit/seed/nut with hard inner "pit" surrounded by an outer shell (i.e., the electrons).References to the above are cheerfully available on request.Anyway, that's the 411 on "nucleus"...in a nutshell.;-)

Answer 2

The English word "atom" comes from the Greek word ἄτομος (átomos) for "indivisible" or "unable to be divided."
