Concept explainers
(a)
Concept introduction: The space filling molecular models represent the atoms and compounds. The same structures indicate the same atoms or compounds. Each sphere indicates an atom and the attached spheres indicate the compound.
(a)

Answer to Problem 1E
Solution: Figure (i)
Explanation of Solution
The figure (i) represents the space filling molecular models of two spheres attached to each other with the same color.
Therefore, figure (i) indicate the diatomic molecule of the same atoms in it. Thus, it corresponds to a pure element.
Figure (i) represent the structure corresponding to pure element.
(b)
Concept introduction: The space filling molecular models represent the atoms and compounds. The same structures indicate the same atoms or compounds. Each sphere indicates an atom and the attached spheres indicate the compound.
(b)

Answer to Problem 1E
Solution: The figures that represent a mixture of two elements are (v) and (vi).
Explanation of Solution
The figures (v) and (vi) represent the space filling molecular models of two differently colored spheres apart from each other.
Therefore, it does not indicate any compound. Instead, it indicates the mixture of two different elements.
Figure (v) and (vi) represent the structures corresponding to a mixture of two elements.
(c)
Concept introduction: The space filling molecular models represent the atoms and compounds. The same structures indicate the same atoms or compounds. Each sphere indicates an atom and the attached spheres indicate the compound.
(c)

Answer to Problem 1E
Solution: The figure that represents a pure compound is (iv).
Explanation of Solution
The figure (iv) represents the space filling molecular models of two spheres attached to each other with the different colors.
Therefore, figure (iv) indicates the diatomic molecule of the different atoms in it. Thus, it corresponds to a pure compound.
Figure (iv) represents the structure corresponding to pure compound.
(d)
Concept introduction: The space filling molecular models represent the atoms and compounds. The same structures indicate the same atoms or compounds. Each sphere indicates an atom and the attached spheres indicate the compound.
(d)

Answer to Problem 1E
Solution: The figures that represent a mixture of an element and a compound are (ii) and (iii).
Explanation of Solution
The figure (ii) represents a space filling molecular model of a diatomic molecule with two spheres of same color attached to each other and a compound with two spheres of different color attached to each other.
Therefore, figure (ii) represents a mixture of diatomic molecule of pure element and a compound.
The figure (iii) represents a space filling molecular model of a monatomic sphere with single spheres of same color apart from each other and a compound with two spheres of different color attached to each other.
Therefore, figure (iii) represents atoms of pure element and a compound.
Figure (ii) and (iii) represent the structures corresponding to a mixture of an element and a compound.
