As you can see in the periodic table below, thehalogensinclude the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). All of them are relatively common on Earth except for astatine. ... Therefore, halogens have seven valence electrons. Is chlorine a ...

gas- a fluid in the gaseous state having neither independent shape nor volume and being able to expand indefinitely halogen- any of five related nonmetallic elements (fluorine or chlorine or bromine or iodine or astatine) that are all monovalent and readily form negative ions ...
Fluorine is the lightest member of the halogen family, elements in Group 17 (VIIA) of the periodic table. The periodic table is a chart that shows how elements are related to one another. These include chlorine, bromine, iodine, and astatine. Fluorine is the most active chemical element, ...
elements with similar and interesting properties: the halogens. Almost all of these reactive elements are pretty familiar, especially chlorine, which most of us eat by the gram every day in the form of table salt. As the neighborhoods of the periodic table go, Group 17 is pretty familiar ...
It is a member of Group 17 (the halogens) of the periodic table. Fluorine readily displaces the other halogens from their salts. It combines spontaneously with most other elements—exceptions are chlorine, nitrogen, oxygen, and the so-called inert gases (helium, neon, argon, krypton, xenon...
