全部 / 所有 / 整个【quánbù / suǒyǒu / zhěnggè】

所有, 整个 and 全部 all translate as "all" or "whole", but they divide things differently. 所有 counts the members of a group; 整个 takes one thing whole; 全部 is the entire amount, however it's made up.

所有: every one of them

所有 goes before a noun, with or without 的, and the sentence usually has 都 before the verb.

• × 所有的学生来了 → 所有的学生都来了

整个: one thing, start to end

整个 goes before a single thing – a day, a city, a room – and covers all of it. It can't count separate members.

• × 所有下午 → 整个下午
• × 整个学生 → 所有学生

全部: the whole amount

全部 can go before a noun like 所有, and it can also follow the noun as an adverb, which 所有 can't. On its own it means "all of it".

• × 书所有看完了 → 书全部看完了

全 alone before a noun or verb is a shorter "whole, entirely": 全家 "the whole family", 全对 "all correct".
