What noble gas would be part of

configuation notion for Mn

Argon

Explanation:

Manganese is an atom with 25 electrons in its orbitals. The orbital notation is shown below:

1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s²

The closest noble gas to manganese is argon with a configuration of:

1s² 2s² 2p⁶ 3s² 3p⁶

Therefore, based on the noble gase Ar, we can write Mn as:

[Ar]3d⁵ 4s²
