Answer to Problem 28E
The element carbon
Explanation of Solution
In the periodic table, the metals are arranged on the left of the periodic table, the nonmetals are arranged on the right of the periodic table and the semimetals are arranged in between the metals and nonmetals.
The elements which have metallic luster, high electropositivity, have high thermal and electrical conductivities and high malleability and ductility are classified as metals.
The elements which are brittle, exist in powdery solids or gaseous form, have high electronegativity and the properties opposite to that of metals are classified as nonmetals.
The elements having properties in between of metals and nonmetals are classified as semimetals.

Concept introduction:
An element is a substance that cannot be broken down into any smaller units. An element can be classified as metal, nonmetal or metalloid. The elements in a modern periodic table are arranged in an increasing order of their atomic number. In this modern periodic table, the horizontal rows are said to be periods and vertical columns are said to be groups. There are seven periods and eighteen groups in a modern periodic table.
