2023年6月30日 · These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Although astatine is radioactive and only has short-lived isotopes, it behaves similarly to iodine and is often included in the halogen group.

The halogens are the elements that form group 17 of the periodic table. They are reactive nonmetals and include fluorine, chlorine, bromine, and iodine. Halogens are highly reactive non-metals.

2024年10月21日 · General physical properties of Group 17 elements. Table shows the physical states and colours of various halogens. The colours of the halogens become darker when going down Group 17. (b) All halogens have low melting and boiling points. The halogen molecules are held together by weak van der Waals forces of attraction.

2023年6月30日 · It can be seen that there is a regular increase in many of the properties of the halogens proceeding down group 17 from fluorine to iodine. This includes their melting points, boiling points, the intensity of their color, the radius of the corresponding halide ion, and the density of the element.

2023年6月30日 · Group 17: Chemical Properties of the Halogens Covers the halogens in Group 17: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). Includes trends in atomic and physical properties, the redox properties of the halogens and their ions, the acidity of the hydrogen halides, and the tests for the halide ions.

2024年4月23日 · This chapter covers the nonradioactive elements of Group 17 (F to I), commonly called the halogens. Many properties of these elements are tabulated. There is extensive coverage of the natural sources and preparations of these elements, their structures, properties,...

Read about group 17 elements, their configuration, physical and chemical properties, their uses, and group 17 periodic table. When we go through the group 17 periodic table, we come across six vital elements: the P-block elements. These elements are- Fluorine (Fl), Chlorine (Cl), Bromine (Br), Iodine (I), Astatine (As), and Tennessine (Ts).

2020年12月21日 · Group 17 Elements and Properties. Group 17 includes Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are collectively known as the halogens (Greek halo means salt and genes born i.e., salt producers). The halogens are highly reactive non-metallic elements.

2023年1月25日 · In the periodic table, the Group 17 elements exist as the second column from the right side. The group 17 elements consist of Fluorine, Chlorine, Bromine, Iodine, Astatine, and Tennessine. The group 17 elements are called halogens. We will study the importance of group 17 elements, their properties, and their uses in this article.
