Period 2 element that forms a +2 ion
WebAug 22, 2024 · The only common example of carbon in a +2 oxidation state is carbon monoxide, CO. Carbon monoxide is a strong reducing agent because it is easily oxidized to carbon dioxide, which has a more thermodynamically stable oxidation state of +4. A period 2 element is one of the chemical elements in the second row (or period) of the periodic table of the chemical elements. The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases; a new row is started when chemical behavior begins to repeat, creating columns of elements with similar properties.
