Normally, the very fact that a verb is a compound verb (whether separable or inseparable) has consequences for the conjugation of the verb. The noun-verbs are an exception: They perfectly behave like simple verbs, as if they did not consist of two words at all:
To order, to arrange in a certain order:
- Rang = rank
- Schikken = to arrange, to suit
The past participle is formed as if the verb were a simple verb:
Let us take rangschikken again:
We get the past participle by "ge + stem + t/d"
ge + rangschik + t = gerangschikt
The number of this type of verbs is quite limited: list of noun verbs
Note that the examples above give you the unstressed personal pronouns. Some pronouns change when they are stressed in a phrase: je/jij, we/wij, ze/zij (both singular and plural).
