The substances listed consist of different types of molecules and atoms. Argon (Ar), nitrogen (N2), neon (Ne), and oxygen (O2) are diatomic or monatomic gases composed of either single atoms or pairs of atoms. Carbon dioxide (CO2) and water (H2O) are compounds made up of multiple types of atoms: carbon and oxygen in CO2, and hydrogen and oxygen in H2O.
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
Co2+ has 25 electrons with the configuration: [Ar] 4s2 3d5 no its [Ar]3d^7
I am assuming that the question is for Co2+ ion. and the answer is [Ar] 3d5 4s2
The main molecules that make up air are nitrogen (N2), oxygen (O2), and small amounts of other gases such as carbon dioxide (CO2), argon (Ar), and trace amounts of water vapor (H2O).

Its composition is nearly all CO2: but it also containsCO2: 96.5%N2: 3.5%SO2: 0.015%Ar: 0.007%H2O: 0.002%CO: 0.0017%He: 0.0012%Ne: 0.0007%
The electron configuration for the Co2 ion is Ar 3d7.
The electron configuration of the Co2 ion is Ar 3d7.
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
The AR (atomic mass) of CO2 (carbon dioxide) is 44 g/mol. The MR (molar mass) of Na2CO3 (sodium carbonate) is 106 g/mol.
