The list of elements in order from most conductive to least conductive is; potassium (K), germanium (Ge), selenium (Se).

Conductivity is a property of metals. The more "metallic" an element is, the greater its conductivity.

The most metallic element in the list is Potassium hence it has the highest conductivity (1.4×107 S/m) followed by germanium which is a semiconductor (2000 S/m). Selenium has the least electrical conductivity.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

did anyone actually do this? like if anyone has submitted this i rly need .
