Answer is (3) - metalloid
Elements in group 14 can be classified as non metals, metalloid and metals. Group 14 has C, Si, Ge, Sn and Pb as its elements. C is a non metal. Si and Ge are metalloids while Sn and Pb are metals.
Metalloids are elements which share both non-metallic and metallic characteristics.
The element in group 14, period 3 on the periodic table is Si. Si is a semiconductor means Si can conduct electricity but not good as metals. Conducting electricity ia one of metallic property.
43 inHg = 43 inHg*2.54cm/in = 109.22cmHg * 10 mm/cm = 1092.2 mmHg
14.7 psi = 760 mmHg
1092.2mmHg * 14.7psi / 760 mmHg = 21.13 psi
Answer: option D. 21.13 psi
