Fluorine is a chemical element with the atomic number 9 and the symbol F. It is the lightest halogen and exists as a highly radioactive, pale yellow diatomic gas under normal conditions. It is extremely reactive as the most electronegative element, reacting with all other elements except argon, neon, and helium.

A potential energy surface (PES) expresses the potential energy of a system, especially a collection of atoms, in terms of a set of parameters, most commonly the atoms’ positions. The surface can describe energy as a function of one or more coordinates; if only one coordinate is present, the surface is referred to as a potential energy curve or energy profile. The analogy of a landscape is useful: the value of the energy (analogy: the height of the land) is a function of two bond lengths for a device of two degrees of freedom (e.g. two bond lengths) (analogy: the coordinates of the position on the ground). Each geometry (both external and internal) of the atoms of the molecules in a chemical reaction is associated with a specific potential energy, according to the Potential Energy Surface. This results in a smooth energy “landscape,” and chemistry can be viewed from a topology standpoint as a result (of particles evolving over “valleys””and passes”).
The PES is a molecule’s energy as a function of its nuclei’s locations (r\). The energy of a system of two atoms is proportional to their separation. At great distances, the energy is zero, implying that there is no interaction. At distances of many atomic diameters, enticing forces prevail, while at extremely near distances, repulsive forces prevail, causing the energy to increase. At the curve’s minimum point, the attractive and repulsive effects are balanced. Plots that depict this relationship will help define specific properties of a chemical bond.
Which particle diagram best represents hydrogen
The structures of elements and compounds decide their properties. An atom is the simplest structural unit of an element. Atoms are very tiny particles. One centimeter is the length of a hundred million (100,000,000) hydrogen atoms placed side by side!
In their molecular form, certain elements are monatomic, meaning they are made up of just one (mon-) atom (-atomic). Helium (He) is an example of a monatomic element (see Fig. 2.8). In their molecular shape, other elements have two or more atoms (Fig. 2.8). Each molecule of hydrogen (H2), oxygen (O2), and chlorine (Cl2), for example, has two atoms. Ozone (O3), another type of oxygen, has three atoms, while sulfur (S8) has eight. A single element’s atoms make up all elemental molecules.
Compound molecules contain atoms from two or more separate elements. Water (H2O), for example, has three atoms: two hydrogen (H) atoms and one oxygen (O). Methane (CH4) is a natural greenhouse gas with five atoms: one carbon (C) and four hydrogen (H) atoms (H, see Fig. 2.9).

This chapter covers the fundamental elements of matter as well as some of the most common classification systems used by scientists to communicate with matter. One of the most difficult aspects of this introduction (and this is true at all levels) is that the language can easily confuse students. The terms ‘atom’ and’molecule’ are often confused, and the distinction between element and compound is often difficult for students to grasp. As a result, these ideas and their explanations appear frequently throughout the chapter. We’ve also provided a number of diagrams depicting how various types of matter would appear on an atomic/molecular scale. Since these atoms and molecules are too small to see even with a microscope, science educators refer to diagrams depicting structures on this scale as “sub-microscopic.” Understanding chemistry requires the ability to visualize chemical events as they would occur on a sub-microscopic scale.
It’s also crucial for students to be able to read and draw sub-microscopic diagrams. To strengthen the ability, we’ve included exercises in which students must make molecules out of plasticine or play dough. Play dough is simple and inexpensive to make; a recipe is included.
