I really need help on this question explain why the relative atomic masses of some elemnts are not exact whole numbers

(edited 7 years ago)

Key word: relative.

Not really. Keyword is atomic.

Relative isotopic refers to......"of one isotope"

Atomic refers to "average mass".....

NB. Full definitions not stated above. OP suggested to find out for sure.

No.

The only isotope with an integer relative isotopic mass is ¹²C.

I do stand corrected. Apology indeed. We usually simplify things in school to make it slightly more convenient for most students to get the difference especially when doing those differences question.😊
