Chapter 2: Problem 32

Give two examples of each of the following: (a) a diatomic molecule containing atoms of the same element, (b) a diatomic molecule containing atoms of different elements, (c) a polyatomic molecule containing atoms of the same element, (d) a polyatomic molecule containing atoms of different elements.

Short Answer

Expert verified
Some examples include: \n(a) Hydrogen (H2) and Oxygen (O2), \n(b) Hydrochloric acid (HCl) and Carbon monoxide (CO), \n(c) Ozone (O3) and Phosphorus pentachloride (P4), \n(d) Water (H2O) and Methane (CH4).

Step by step solution

01

Identify Diatomic Molecules of the Same Element (Homonuclear)

A molecule composed of two atoms of the same element is a homonuclear diatomic molecule. Some examples are Hydrogen (H2) and Oxygen (O2), they both consist of two atoms of the same element.
02

Identify Diatomic Molecules of Different Elements (Heteronuclear)

A molecule composed of two atoms of different elements is a heteronuclear diatomic molecule. Examples of these molecules are Hydrochloric acid (HCl) and Carbon monoxide (CO), they consist of two atoms but of different elements.
03

Identify Polyatomic Molecules of the Same Element

A polyatomic molecule is a molecule composed of more than two atoms. If these atoms are of the same element they form a homonuclear polyatomic molecule. Examples are Ozone (O3) and Phosphorus pentachloride (P4), which are composed of three and five atoms respectively of the same element.
04

Identify Polyatomic Molecules of Different Elements

Polyatomic molecules can also be composed of different elements. Examples of these are water (H2O) and methane (CH4). Even though they are composed of more than two atoms, these atoms come from different elements.
