Asked in Chemistry, Name Origins
Where did the name halogen come from?
Halogens are named for the fact that they can form compounds with almost every metal. Those compounds form salts so the halogens are known as "salt formers" or halogens. Halogens are named for the fact that they can form compounds with almost every metal. Those compounds form salts so the halogens are known as "salt formers" or halogens. ...
Asked in Chemistry, Atoms and Atomic Structure
An atom that contain seven electrons in its outer shell would most likely form a ion?
Atoms that have seven electrons in their outer shell belong to Group XVII, or halogens. Halogens form ionic compounds with alkali metals to form salts. ...
Asked in Chemistry
Why do halogens form compounds with alkali metals?
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist. ...
Asked in Noble Gases
How do the properties of the halogens and noble gases compare?
They are completely different Noble gases are colorless, monoatomic gases; the halogens are diatomic, colored and there form at room temperature is F, gas, Cl, gas, Br, liquid I, solid. Nobel gases are chemically unreactive, helium and neon have no known compounds, a few very reactive compounds are known for the rest. The halogens are all reactive, fluoringe is the most reactive. One or more of the halogens will form compounds with all of the other elements apart from the noble gases. (apart...
Asked in Chemistry
What element is most likely to form negative ions?
The elements that are most likely to form negative ions are the halogens. Halogens have 7 valence electrons and will readily acquire an 8th to form an anion. ...
Why do group 1 metals readily form compounds with group 7 halogens?
this is because group 1 is very active and has 1 electron needed by halogens for them to become stable ( have a filled valence outer shell). Thus group 1 metals readily form compounds with group 7 ...
What are the most common elements found in organic compounds?
Almost all organic compounds contain carbon. Almost all organic compounds have hydrogen as well. The most common other elements in organic compounds are oxygen, nitrogen, sulfur, and the halogens. ...
