Will cooked salmon go bad if left out for 7 hours uncovered?

Yes, cooked salmon left out uncovered for 7 hours can go bad. According to food safety guidelines, perishable foods should not be left at room temperature for more than 2 hours, as bacteria can grow rapidly in the "danger zone" between 40°F and 140°F. Consuming salmon that has been left out for that long poses a risk of foodborne illness. It's best to refrigerate leftovers promptly to ensure safety.
