Answer 2

Answer:

Concept:

The oxidation state, often known as the oxidation number, in chemistry refers to the hypothetical charge that an atom would have if all of its links to other atoms were entirely ionic. It describes how much an atom has oxidized (lost electrons) in a chemical complex. The oxidation state can theoretically be positive, negative, or zero. Although nature does not include entirely ionic bonds, it does contain numerous strong ionic bonds, making the oxidation state a reasonable predictor of charge. The formal charge or any other genuine atomic attribute of an atom is not represented by the oxidation state of that atom. This is especially true for high oxidation states, where the amount of ionization energy needed to create a multiply positive ion is much more than the amount of energy available in chemical reactions. A compound's atoms' oxidation states can also change based on the electronegativity scale that was used to calculate them. An atom's oxidation state in a compound is thus just a formalization. Nevertheless, it is crucial to comprehend inorganic compound nomenclature rules. Additionally, a number of chemical reaction findings can be fundamentally described in terms of oxidation states.

Given:

Find the correct answer for the given question

Answer:

The correct answer is option is (b). Ru and Os

In the current periodic table, RuO4 and OsO4 have the highest amounts of oxidation (+8).

Ru (ruthenium) and Os are the two transition metals that exhibit the oxidation state of +8. (osmium).

The higher electronegative elements like O, F, and Cl are what give the 4d and 5d elements their greatest oxidation states.

For instance, RuO4 and OsO4.

Ru Its atomic number 44 identify the chemical element ruthenium. It is an uncommon transition metal from the periodic table's platinum group. Rutanium is inert to the majority of other compounds, just like the other platinum group metals. German-Baltic-German scientist born in Russia

At Kazan State University, Karl Ernst Claus made the element's discovery in 1844. He gave it the Russian name ruthenium.

The chemical element osmium has the atomic number 76 and the letter Os as its symbol. It is a hard, brittle, bluish-white transition metal from the platinum family that is usually found in platinum ores and is used as a trace element in alloys. The densest naturally occurring element is osmium. Its density, as determined experimentally by X-ray crystallography, is 22.59 g/cm3. Its alloys with platinum, iridium, and other platinum-group metals are used by manufacturers to create electrical contacts, nib tips for fountain pens, and other items that need to be extremely durable and hard.
