Model | Rank | Descriptor | Underlying property | RI (%) |
---|---|---|---|---|
K | 1 | log(V) | volume per atom | 46.6 |
2 | μ1(Rn) | row number | 24.5 | |
3 | Ec | cohesive energy | 19.4 | |
4 | μ−4(X) | electronegativity | 9.5 | |
G | 1 | Ec | cohesive energy | 37.0 |
2 | log(V) | volume per atom | 35.9 | |
3 | μ−3(Rn) | row number | 13.8 | |
