Pronouns are words that replace nouns. Examples include:
* Personal pronouns: I, you, he, she, it, we, they
* Possessive pronouns: mine, yours, his, hers, its, ours, theirs
* Reflexive pronouns: myself, yourself, himself, herself, itself, ourselves, yourselves, themselves
"No" is an adverb that means "not any" or "not at all." It can be used to negate a verb, adjective, or other adverb.
Example:
* Correct: There are no apples left. (No modifies the noun "apples")
* Incorrect: No is in the kitchen. (No is not a pronoun and cannot replace a noun)
To use a pronoun in this sentence, you could say:
* He is in the kitchen. (He replaces the noun "person")
