Question

Where are the most active nonmetals located?

Answer 1

The periodic table, commonly known as the periodic table of elements, is a tabular representation of chemical elements organised by atomic number, electron configuration, and recurrent chemical characteristics. The table's structure reveals periodic patterns. Metals are on the left and nonmetals are on the right in the table's seven rows, known as eras. The elements in the columns, referred to as groupings, have comparable chemical properties.

Complete answer:
The halogens are a set of five chemically related elements in the periodic table: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (A) (At). Tennessine (Ts), an artificially produced element, may also be a halogen. This group is designated as group 17 in contemporary IUPAC nomenclature. The word "halogen" literally means "salt-producing." When halogens react with metals, a variety of salts are produced, including calcium fluoride, sodium chloride, 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.
In significant concentrations, halogens can be toxic or fatal to living organisms due to their strong reactivity. Because of their large effective nuclear charge, atoms have a high electronegativity, resulting in strong reactivity. Because halogens contain seven valence electrons in their outermost energy level, they can meet the octet rule by interacting with atoms of other elements. Fluorine is the most reactive of all the elements; it is the only element that is more electronegative than oxygen, attacks otherwise inert materials like glass, and forms compounds with the normally inert noble gases. It is an extremely poisonous and caustic gas.
Fluorine's reactivity is such that it can react with glass in the presence of modest amounts of water to create silicon tetrafluoride if used or kept in laboratory glassware. As a result, fluorine must be treated with materials like Teflon (which is an organofluorine compound), very dry glass, or metals like copper or steel, which have a protective fluoride coating on their surface. Fluorine's high reactivity allows it to form some of the strongest bonds, particularly with carbon. Teflon, for example, is a fluorine-carbon alloy that is very resistant to heat and chemical assaults and has a high melting point.
Hence Group 17 is correct.

Note:
The chemical bond energy of the halogens moves from the top to the bottom of the periodic table column, with fluorine deviating slightly. It has the maximum bond energy in compounds with other atoms, but it has relatively weak bonds inside the diatomic molecule, which follows a pattern. This indicates that as you move down Group 17 in the periodic table, the reactivity of the elements diminishes as the atoms get bigger.
