What does the prefix mono mean in a chemical formula?
The prefix ‘mono’ is only used on the second non-metal in the chemical formula. There shouldn’t be two vowels in a row. For example, when you have ‘mono’ in front of ‘oxide’ it is written ‘monoxide’, not ‘monooxide’.

What is the origin of the Greek word mono?
“mono-” is from Greek monos = “alone”. “un” = 1 and “nona-” = 9 are from Latin. The others are derived from Greek numbers. The forms 100 and upwards are not correct Greek. In Ancient Greek, hekaton = 100, diakosioi = 200, triakosioi = 300, etc. The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry.
