Welcome to the community...!
Ads stay pending for approval, not keywords. When ads get approval, keywords trigger them based on search queries.
Please find more about adwords ad approval process below
Check your ad approval status
At times it can take up to 3 business days to get the ads approved.
What type of ads do you have? Image ads takes longer time than text ads for approval.
Hope this helps,
