Identify the correct statements I ) Germanium exists only in traces. II ) The order of electronegativity of Si ,   Ge ,   Sn is Sn > Ge > Si III ) All group 14 elements are available in solid state

Step-by-step solution

Germanium exists only in traces(1.5 ppm) and mainly recovered from flue dust arising from the roasting of zinc ores. The electronegativity of group 14 elements decreases from carbon to silicon and remains constant from silicon to sin and then slightly increases for lead. C > Si ≈ Ge ≈ Sn < Pb . All the group 14 elements are available in solid state in their native state.
