Professor PC Thomas Classes · Answer

The $14^{	ext {th }}$ group elements arranged in the decreasing order of abundance $\mathrm{Si}>\mathrm{C}>\mathrm{Pb}>$ $\mathrm{Sn}>\mathrm{Ge}$\ $\mathrm{Si}=282000 \mathrm{ppm}, \mathrm{C}=200 \mathrm{ppm}, \mathrm{Pb}=14 \mathrm{ppm} \quad \mathrm{Sn}$ $=2.3 \mathrm{ppm}, \mathrm{Ge}=1.5 \mathrm{ppm}$\
