Correct spelling, explanation: the word excellence, like many others in English, must be spelled with a double consonant. In this case, it is the letter -l. Remember that this noun is borrowing, so if you’re not sure how to write it, look up the etymology. You’ll clearly see that the only correct version is excellence, not excelence.

Incorrect spelling, explanation: many words in English come from other languages. It is no different in the case of the word excellence, which comes from Latin and Old French.
