Interpretation: The location of metalloids in the periodic table needs to be determined and compare their properties with those of metals and non-metals.
Concept Introduction: Metalloids are chemical elements that have physical and chemical properties intermediate between those of metals and non-metals. There are six metalloids in the periodic table.
Answer to Problem 120A
Metalloids belong to the p-block elements which are placed on the right side of the periodic table. Their chemical and physical properties fall in between those of metals and non-metals.
Explanation of Solution
Metalloids are placed in the p-block in the periodic table. There are six metalloids in the periodic table that are arranged diagonally across the p-block extending from boron to tellurium. They are placed as the dividing line between metals and non-metals. Since they are placed in between metals and non-metals in the periodic table, their properties are also intermediate to them.
