Octa- the prefix means eight. Penta- the prefix means five.
The classical Latin and Greek languages are the sources of the prefixes 'octa-', 'hexa-', and 'penta-'. The prefixes respectively mean 'eight', 'six', and 'five'. They come into English by way of the Latin of the ancient Romans and by way of the even earlier Greek of the ancient Greeks.

In general, poly. Specifically, there are infinite prefixes. Examples include deca, octa, and penta.
The prefixes in chemistry are used to indicate the quantity of atoms in a chemical compound. Common prefixes include mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, octa-, nona-, and deca-. These prefixes are placed before the element name to specify the number of atoms present.
No, "penta" does not mean six; it means five. The prefix for six is "hexa." These prefixes are derived from Greek, where "penta" signifies five (like in pentagon), and "hexa" signifies six (as in hexagon).
mono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nano-9 deca-10
5 = penta 6 = hexa 7 = hepta 8 = octa 9 = nona 10 = deca
The formula for pentanitrogen octatelluride is N₅Te₈. This compound consists of five nitrogen atoms and eight tellurium atoms, reflecting its name. The formula is derived from the prefixes "penta-" for five and "octa-" for eight.
The Greek prefixes for 3, 5, and 7 are "tri-", "penta-", and "hepta-" respectively.
Have someone help you edit your question; we can't quite understand what you want to know. There are many different kinds of polygon, polygon is a general term for any enclosed plane figure with straight sides. If you take away the 'poly' and add other prefixes like penta-, hexa- octa- or deca-, that tells you how many sides that polygon has. Penta means 5, hexa means six, octa means 8, deca means 10. There are many other ways to describe polygons.
Improved Answer:- They mean 6 and 8 respectively
Penta= 5. Octa = 8. So pentachlorine octaoxide is Cl5O8
