7A group(s) of the periodic table is described by The free elements are strong oxidizing agents and form monatomic ions and oxoanions.
A chemical element that has no chemical bonds or combinations with other elements is said to be a free element. The oxygen molecule (O2) and carbon are two examples of elements that can be found devoid of other elements. Free element atoms all have an oxidation number of zero. They hardly ever form atom-to-atom bonds. The periodic table currently lists 118 elements. Numerous substances have only been discovered in research facilities and nuclear accelerators. You might then wonder how many elements are naturally occurring. The standard textbook response is 91.
Strong oxidizing agents are often made up of elements that have high oxidation states or high electronegativity and that gain electron during a redox process (Figure 1). Osmium tetroxide, permanganate, and hydrogen peroxide are a few examples of strong oxidizers.
