Question

What is the atomicity of Halogens?

Answer 1

The total number of atoms in a molecule is known as atomicity. Each molecule of oxygen, for example, is made up of two oxygen atoms. As a result, the atomicity of oxygen is 2. The term atomicity is often used interchangeably with the term valency in older settings.

Complete answer:
The word "halogen" literally means "salt-producing." When halogens react with metals, a variety of salts are produced, including calcium fluoride, sodium chloride (table salt), silver bromide, and potassium iodide. At normal temperature and pressure, the halogens are the only periodic table group that contains elements in three of the major states of matter. When halogens are linked to hydrogen, they all produce acids. The majority of halogens are produced from minerals or salts.
The halogens are a class of chemical elements with a seven-electron outer shell. This means that they must gain a single electron to achieve noble gas electron configurations. A covalent compound is formed when two halogen atoms are combined. They can share an electron and have a full octet because of the covalent connection. Halogen has an atomic number of two.
The halogens combine to produce diatomic compounds with homonuclear nuclei (not proven for astatine). Chlorine and fluorine are classified as "elemental gases" because of their modest intermolecular interactions. As the atomic number grows, the elements become less reactive and have higher melting temperatures. Stronger London dispersion forces generated by more electrons result in greater melting points.

Note:
At normal temperature and pressure, the halogens are the only periodic table group that contains elements in three of the major states of matter. When halogens are linked to hydrogen, they all produce acids. The majority of halogens are produced from minerals or salts. Chlorine, bromine, and iodine, the middle halogens, are frequently employed as disinfectants. The most common type of flame retardant is organic bromides, but elemental halogens are hazardous and can be fatal.
