How does fluorine react with sodium?
Fluorine reacts vigorously with sodium to form sodium fluoride. This reaction is highly exothermic and releases a significant amount of energy in the form of heat and light. The reaction is also highly explosive and should be carried out with caution. Sodium fluoride is a white solid compound that is commonly used in toothpaste and water fluoridation.

What is the flame color of fluorine?
The flame color of fluorine is a pale yellow-green. When fluorine gas is burned, it produces a characteristic yellow-green flame due to the excitation of electrons in the gas molecules. This color is often used as a way to identify the presence of fluorine in chemical reactions or experiments.
-
Why does fluorine boil at 188°C?
Fluorine boils at 188°C because it has a very low boiling point compared to other elements due to its small atomic size and high electronegativity. The small size of the fluorine atom allows for strong intermolecular forces to be easily overcome, leading to its low boiling point. Additionally, the high electronegativity of fluorine results in strong dipole-dipole interactions between molecules, further contributing to its low boiling point.
-
In which xenon compounds is fluorine involved?
Fluorine is involved in the formation of xenon tetrafluoride (XeF4) and xenon hexafluoride (XeF6). These compounds are formed by the reaction of xenon with an excess of fluorine gas. Fluorine acts as the oxidizing agent in these reactions, allowing xenon to achieve a higher oxidation state than its usual zero oxidation state in elemental form.

What is the relationship between fluorine and chlorine?
Fluorine and chlorine are both halogens and are located next to each other on the periodic table. They share similar chemical properties due to their outer electron configuration, but they also have distinct differences. Fluorine is the most electronegative element, while chlorine is slightly less electronegative. Both elements can form compounds with other elements, but their reactivity and properties may vary.
-
What is the electronegativity of fluorine and francium?
Fluorine has the highest electronegativity of all elements, with a value of 3.98 on the Pauling scale. Francium, on the other hand, has one of the lowest electronegativities, with a value of 0.7 on the Pauling scale. This means that fluorine has a strong tendency to attract electrons, while francium has a weak tendency to attract electrons.
-
What is the profile of the atom Fluorine?
Fluorine is a chemical element with the atomic number 9 and symbol F. It belongs to the halogen group on the periodic table, making it highly reactive. Fluorine is a pale yellow gas at room temperature and is the most electronegative element, meaning it has a strong tendency to attract electrons. It is commonly found in compounds like fluoride minerals and is essential for various industrial and biological processes.
-
Why do nitrogen and fluorine occur as molecules?
Nitrogen and fluorine occur as molecules because they are diatomic elements, meaning they naturally exist as molecules composed of two atoms of the same element bonded together. Nitrogen forms N2 molecules, while fluorine forms F2 molecules. This occurs because both elements have high electronegativity and prefer to form strong covalent bonds with themselves rather than with other elements. As a result, they exist as stable diatomic molecules in their natural state.
