What else can I help you with?
Are halogens the basis for all fossil fuels?
No, halogens are not the basis for all fossil fuels. Fossil fuels primarily consist of hydrocarbons, which are compounds made of hydrogen and carbon. Halogens, such as chlorine, fluorine, bromine, and iodine, do not play a significant role in the formation of fossil fuels.
Why are the halogens not found naturally in the earth's crust as the pure elements?
The halogens are not found naturally in the earth's crust as pure elements because of their extreme reactivity. Because the halogens are close to having completely filled electron shells, they will often react with other substances in order to gain an electron. As an especially noteworthy case, fluorine is the most reactive of the halogens (and elements in general), and will even react with glass. Therefore, the halogens are found naturally as compounds, not pure elements.
Does halogens have high or low reactivity?
Halogens have high reactivity because they have a strong tendency to gain an electron to achieve a stable electron configuration. This reactivity decreases as you move down the group from fluorine to iodine.
What are the elements fluorine chlorine bromine and iodine called?
These elements are typically called halogens, and they are found in Group 17 of the periodic table.
Group containing iodine and chlorine?
The group containing iodine and chlorine is called the halogens. Halogens are a group of non-metal elements that are highly reactive and include fluorine, chlorine, bromine, iodine, and astatine. They exhibit similar chemical properties due to their outermost electron configuration.
Elements in Group 17 are all called?
Halogens Apex ;)
What are three members of the halogen group?
fluorine, chlorine, bromine, iodine and astatine are the five halogens
Halogens are only found in nature as what?
Halogens are found in nature primarily as salts, such as sodium chloride (table salt) or potassium iodide. They are highly reactive nonmetals that readily form ionic bonds with metals to create mineral salts.
Are halogens the only periodic group that contains all three phases of matter?
No, the periodic group that contains all three phases of matter is group 17 - the halogens. They exist as gases (fluorine, chlorine), liquid (bromine), and solids (iodine, astatine) at room temperature.
What are halogens and where are they located?
Halogens are in Group 7
Why are halogens known as salts?
Halogens are not salts but they are chemical elements; halogens can form salts reacting with metals.
Halogens are radioactive or not?
No, halogens are reactive however and can be dangerous.
Are halogens reactive?
Yes, halogens are extremely reactive.
How are halogens like metals?
Halogens are not like metals. Halogens are elements missing one electron for full valency.
Which non-metals are chemically most reactive?
halogens
What is another name for the group 17 elements?
Another name for Group 17 (VIIA) Elements is Halogens.
