This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
The noble gas configuration of chromium is [Ar] 3d5 4s1. It is written this way because the electron configuration of argon (1s2 2s2 2p6 3s2 3p6) is the closest noble gas configuration to chromium, with 3d5 4s1 representing the additional electrons in the chromium atom.
The electron configuration of a neutral chromium atom is [Ar]3d54s1. The electron configuration for manganese is [Ar]3d54s2. The first electron removed from a chromium atom is the single 4s electron, leaving the electron configuration [Ar]3d5. The first electron removed from a magnesium atom is one of the 4s2 electrons, leaving the electron configuration [Ar]3d54s1. Removal of a second electron from a chromium atom involves the removal of one of the 3d electrons, leaving a configuration of [Ar]3d4, which is not a very stable configuration, and requires more energy to achieve. Removal of a second electron from a magnesium atom involves the removal of the second 4s electron, leaving a configuration of [Ar]3d5, which is more stable and requires less energy to achieve.
Yes, Cr3+ will have a noble gas configuration. It will have the electron configuration of argon (Ar) due to the loss of three electrons from the chromium atom.

The electron configuration of a chromium atom is 1s2 2s2 2p6 3s2 3p6 4s1 3d5.
The electron configuration for Chromium (Cr) is [Ar] 3d^5 4s^1. The electron configuration for Chromium II (Cr^2+) is [Ar] 3d^4.
The electron configuration of a chromium atom in its 2 oxidation state is Ar 3d4 4s0.
Vanadium ( V) has that configuration. Its atomic number is 23.
Chromium (24Cr) electron configuration: [Ar] 3d5 4s1 Complete [1s2, 2s2 2p6, 3s2 3p6] 3d5, 4s1
This electron configuration belongs to the element chromium, which has the atomic number 24. Chromium is a transition metal element.
The electron configuration of a chromium II ion (Cr^2+) is [Ar] 3d^5. Chromium normally has an electron configuration of [Ar] 3d^5 4s^1, but when it loses two electrons to form the Cr^2+ ion, the 4s^1 electron is lost first, resulting in a 3d^5 configuration.
The electron configuration of a chromium (Cr) 3 ion is Ar 3d3 4s0.
Chromium has 24 electrons. Its electron configuration is [Ar]3d5 4s1. This configuration allows for the half-filled d orbital, which gives chromium additional stability.
Chromium has a half filled D orbital so is stable.
The electronic configuration of tin is: [Kr]D10.5s2.5p2.The electronic configuration of chromium(2+) is correct.
