highly reactive with alkali metals and alkaline earth metals
The most common halogen on the periodic table would have to be either chlorine or iodine.
Iodine
A halogen pan is a type of cookware that is compatible with halogen cooktops. They are usually made of stainless steel or special heat-conductive materials to maximize heat transfer and efficiency. Halogen pans are designed to work well with the specific heating properties of halogen stovetops.
The halogen in sodium hypochlorite is chlorine. Sodium hypochlorite is the chemical compound with the formula NaClO, where chlorine is the halogen element that provides its disinfecting properties.
low boiling point and high reactivity
Iodine
Helium, fluorine, and chlorine are all elements found on the periodic table. They belong to different groups: helium is a noble gas, fluorine is a halogen, and chlorine is also a halogen. They have different properties and reactivity levels.
Iodine
Halogens are expected to have properties such as high reactivity, tendency to form salts with metals, and exhibit diatomic molecules in their elemental form. They are typically nonmetals, have high electronegativity, and appear in Group 17 of the periodic table. Some common halogens include fluorine, chlorine, bromine, and iodine.
Chlorine in domestic instance and flourine in atmosphere.
Fluorine is a halogen that easily combines with carbon compounds to provide new properties to the molecule. This process, known as fluorination, often improves stability, reactivity, and bioavailability of the compound.
Halogen vapors are highly reactive due to their ability to gain electrons, making them strong oxidizing agents. They also have distinct colors, ranging from yellow (for chlorine) to orange (for bromine) to purple (for iodine).
