Answer

We can rank the nuclides in decreasing order of the number of neutrons: $^6_3Li \gt ~^4_2He = ~^7_5B \gt ~^3_2He =~ ^2_1H = ~^4_3Li$

Work Step by Step

The upper number is the total number of nucleons (neutrons and protons), while the bottom number is the number of protons. Therefore, to find the number of neutrons, we subtract the lower number from the upper number. We can rank the nuclides in decreasing order of the number of neutrons: $^6_3Li \gt ~^4_2He = ~^7_5B \gt ~^3_2He =~ ^2_1H = ~^4_3Li$
