Why is coordination number of cobalt 6?
In the complex ion, `[Co(en_(3))^(3+)]` , the coordination number (CN) of Co is 6 because en (ethane -1,2-diamine) is a bidenate ligand and hence provides two donor atoms. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
What type of element is cobalt?
transition metals
Cobalt is a lustrous very hard silvery metal belonging to a group called the “transition metals”. It is one of only 3 ferromagnetic transition elements along with iron and nickel.
Is cobalt a compound?
Cobalt is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is Co and its atomic number is 27, which means that a cobalt atom has 27 protons in its nucleus.
What is cobalt compound?
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth’s crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
What elements does cobalt bond with?
Cobalt is one of the three metals that are ferromagnetic at room temperature. It dissolves slowly in dilute mineral acids, does not combine directly with either hydrogen or nitrogen, but will combine, on heating, with carbon, phosphorus, or sulfur.
What are the oxidation number and coordination number of cobalt in the complex Co en 2br₂ CL respectively?
What is the coordination number of cobalt in K Co Co 4?
(iv) -3. We know that CO is a neutral ligand and K carries a charge of +1. Therefore, the complex can be written as K+ [Co(CO)4]-. Therefore, the oxidation number of Co in the given complex is -1.
