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.
What else can I help you with?
Is Ar a atom or molecule?
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
What is the electron configuration of the ion Cobalt2?
Co2+ has 25 electrons with the configuration: [Ar] 4s2 3d5 no its [Ar]3d^7
What notation is the correct noble gas configuration for Co2?
I am assuming that the question is for Co2+ ion. and the answer is [Ar] 3d5 4s2
What molecule make up air?
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).
How many electrons are in an atom of 40 18 ar?
An atom of (^{40}_{18}\text{Ar}) (argon) has 18 electrons. This is because the number of electrons in a neutral atom is equal to the number of protons, and for argon, the atomic number is 18. Thus, an atom of argon has 18 protons and 18 electrons.

What is the electron configuration for the Co2 ion?
The electron configuration for the Co2 ion is Ar 3d7.
What is the electron configuration of the Co2 ion?
The electron configuration of the Co2 ion is Ar 3d7.
What is the AR or MR value of Co2 and NA2CO3?
The AR (atomic mass) of CO2 (carbon dioxide) is 44 g/mol. The MR (molar mass) of Na2CO3 (sodium carbonate) is 106 g/mol.
What is the electron configuration of the ion Cobalt2?
Co2+ has 25 electrons with the configuration: [Ar] 4s2 3d5 no its [Ar]3d^7
What notation is the correct noble gas configuration for Co2?
I am assuming that the question is for Co2+ ion. and the answer is [Ar] 3d5 4s2
What is the electron configuration of an atom of sodium?
[Ar] 3s1
What molecule make up air?
