I - Iodine, 54 so if you were to find the free electrons per unit volume, you'd find that there are less and less as you go down the group. Usually, there is no need to store these elements in oil, unlike the group one elements. Notice that the Group 2 elements have much lower electron affinities than the Group 1 elements, with beryllium and magnesium even having positive electron affinities. SPECIFICATIONS Resistivity is commonly represented by the Greek letter ρ (). For a metal, alkali earth metals tend to have low melting points and low densities. Electrical conductivity depends on declocalised electrons. N - Nitrogen, 9 Pm - Promethium, 62 Group 1 metals are less reactive than group 2 metals. The ES-2 Electrical Conductivity & Temperature Sensor is designed to measure the electrical conductivity (EC) and temperature of water in a pipe or tank.
