Chapter 4, Problem 4.5QP

(a)

Interpretation Introduction

Interpretation:

The given set of substances has to be classified as a metal, a non-metal, or a metalloid.

Concept Introduction:

Metals have typical physical properties such as hard when in solid state, shiny, ductile, malleable, very dense, high melting points and boiling points and have good electrical and thermal conductivity.  Metals are located in the middle of and on the left of the standard periodic table.

Non-metal is an element that doesn’t exhibit characteristic properties of metals as hardness, ductile, lustre or flexibility.  Non-metals are soft, brittle and good insulators of heat and electricity.  Non-metals are located on the far right side of the standard periodic table, except hydrogen, which is located in the top corner.

An element with properties intermediate between that of a metal and a non-metal especially has the appearance of a metal but reacts chemically more as a non-metal.  Most metalloids behave as semiconductors.  In the standard periodic table metalloids occur along a diagonal line through the p block, from boron to polonium.
