Chapter 3, Problem 3.66EP

(a)

Interpretation Introduction

Interpretation:

The elements that are located in period 3 of the periodic table have to be chosen from carbon, chlorine, phosphorus, calcium, copper and bromine.

Concept Introduction:

Periodic law states that if the elements are arranged in increasing order of atomic number, then the elements with similar chemical properties occur at regular intervals or periodic intervals.  The elements are arranged in a periodic table in which the arrangement was based on the atomic number of the elements and the elements that have similar chemical properties are positioned in vertical columns.

Location of an element in a periodic table can be given by the period number and the group number.  The horizontal row in a periodic table where the elements are present is known as Period.  The vertical column in a periodic table where the elements are present is known as Group.

(b)

Interpretation Introduction

Interpretation:

The elements that belong to halogen family have to be chosen from carbon, chlorine, phosphorus, calcium, copper and bromine.

(c)

Interpretation Introduction

Interpretation:

The elements that readily conduct heat have to be chosen from carbon, chlorine, phosphorus, calcium, copper and bromine.

(d)

Interpretation Introduction

Interpretation:

The elements that have its nuclear charge less than +16 has to be chosen from carbon, chlorine, phosphorus, calcium, copper and bromine.
