Yes, the term "pentaoxide" and "pentoxide" can both be used to refer to a compound containing five oxygen atoms. The prefix "penta-" indicates five, and "oxide" refers to a compound containing oxygen. Therefore, both terms are acceptable and interchangeable when describing a compound with five oxygen atoms.
