The halogen group in the Periodic Table is read from top to bottom.
The halogens are, from the top;-
Fluorine
Chlorine
Bromine
Iodine
Astatine ( not fully characterised)
Tennessine (A.No. 117 ; not fully characterised).
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.
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.
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.
These elements are typically called halogens, and they are found in Group 17 of the periodic table.
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.
Halogens Apex ;)
Halogens with lower atomic number are more reactive and less dense. Also iodine is solid, bromine liquid and the first halogens are gases.
Only four compounds with Cl and Br were obtained up today.
Fluorine has the largest first ionization energy among the halogens.
Halogens, specially fluorine
Halogens are in Group 7
Halogens are not salts but they are chemical elements; halogens can form salts reacting with metals.
Halogens are group seven on the Periodic Table, this means they take electrons during bonding as opposed to giving them. Halogens are often used for cleaning and disinfecting, most notably in pools. They are also poisonous and were introduced into warfare in the first world war. Halogens are common in acids such as hydro-CHLORIC acid.
No, halogens are reactive however and can be dangerous.
Yes, halogens are extremely reactive.
Halogens are not like metals. Halogens are elements missing one electron for full valency.
