The largest possible value of the fundamental unit of charge is $1.33\times 10^{-19}~C$
We can find the difference between each successive charge: $(3.99\times 10^{-19}~C)-(2.66\times 10^{-19}~C) = 1.33\times 10^{-19}~C$ $(6.65\times 10^{-19}~C)-(3.99\times 10^{-19}~C) = 2.66\times 10^{-19}~C$ $(9.31\times 10^{-19}~C)-(6.65\times 10^{-19}~C) = 2.66\times 10^{-19}~C$ $(10.64\times 10^{-19}~C)-(9.31\times 10^{-19}~C) = 1.33\times 10^{-19}~C$ The largest possible value of the fundamental unit of charge is $1.33\times 10^{-19}~C$ We can see that each charge is a multiple of this value: $2\times (1.33\times 10^{-19}~C) = 2.66\times 10^{-19}~C$ $3\times (1.33\times 10^{-19}~C) = 3.99\times 10^{-19}~C$ $5\times (1.33\times 10^{-19}~C) = 6.65\times 10^{-19}~C$ $7\times (1.33\times 10^{-19}~C) = 9.31\times 10^{-19}~C$ $8\times (1.33\times 10^{-19}~C) = 10.64\times 10^{-19}~C$
