Co is cobalt and is not a noble gas. Cobalt is a transition metal. Its electron configuration is [Ar]3d74s2.
[Ar] 4s2 3d7
The element with this electron configuration is manganese (Mn), which has 25 electrons.
No, let's try to take carbon monoxide in room temperature, it's not odorless
Yes most things can be a gas as long as there at the correct temperature so carbon could be a gas
CO₂ is an acidic oxide. Whether or not CO₂ can be considered "inert gas" depends on a number of factors. The most obvious of which being phase. Dry ice, for instance, is solid CO₂ & can't very well be considered an "inert gas". At temperatures below 300C, gaseous CO₂ can be considered "inert gas" as is commonplace in the food industry. However, at higher pressures CO₂ & H₂O combine to form aqueous H₂CO₃ (carbonated water). Also, gaseous CO₂ is readily broken down into component elements during photosynthesis. At temperatures exceeding 300C a reaction occurs between CO₂ & hydrogen know as the Sabatier reaction. Elemental hydrogen exists only in trace quantities within Earth's atmosphere, so this reaction is quite rare outside the lab. CO₂ is often mistakenly called "inert gas" by those in the welding industry. CO₂ is actually an 'active shielding gas' in this context as the welding arc causes electron dissociation, converting CO₂ into carbon monoxide & oxygen. The released oxygen generates heat, thus making CO₂'s role "active". Meanwhile, excess CO₂ "shields" the molten 'puddle' from unwanted atmospheric gas. Adding argon to the mix creates a 'semi-inert shielding gas', but that's for another lesson. Generally speaking, the only truly 'inert gases' are group 18 (noble gasses) & even they have their limits.
The noble gas configuration for Cobalt (Co) is [Ar] 3d7 4s2.
[Ar] 4s2 3d7
[Ar] 4s2 3d7
[Ar] 4s2 3d7
[Ar] 4s2 3d7
The noble gas configuration for cobalt (Co) is [Ar] 3d7 4s2, where [Ar] represents the electron configuration of argon. This notation indicates that cobalt has the same electron configuration as argon, with an additional 3d7 4s2 electron configuration specific to cobalt.
The electron configuration Ar4s²3d⁷ corresponds to the element cobalt (Co), which has an atomic number of 27. In this configuration, "Ar" represents the noble gas argon, which accounts for the first 18 electrons. The 4s² indicates two electrons in the 4s subshell and the 3d⁷ indicates seven electrons in the 3d subshell, totaling 27 electrons for cobalt.
The element with this electron configuration is manganese (Mn), which has 25 electrons.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
