9. Which statement concerning average nuclear binding energy per gram of nuclei is false?
For nuclei with small mass numbers, it increases rapidly with increasing mass number.
It reaches a maximum around mass number 50.
It decreases slowly with increasing mass number for nuclei with mass numbers greater than 50.
The nuclei with the highest binding energies (mass numbers 40 to 150) are the most stable.
Nuclei with mass numbers greater than 210 can easily be decomposed into protons and neutrons. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50
