No Such ... all atoms have an electron configuration, yet Ca++ is not a noble gas.
[Ar] 4s2
The noble gas core notation for Calcium is [Ar]4s2. This notation represents the electron configuration of Calcium by using the nearest noble gas (Argon) as a reference.
The electron configuration for a calcium atom, which has an atomic number of 20, is 1s² 2s² 2p⁶ 3s². This notation indicates that calcium has two electrons in the first energy level (1s), eight in the second level (2s and 2p), and two in the third level (3s). The full configuration can also be abbreviated as [Ar] 4s², where [Ar] represents the electron configuration of argon, the preceding noble gas.

The electron configuration for calcium is 1s2 2s2 2p6 3s2 3p6 4s2. Calcium has 20 electrons, so it fills the 4s subshell before the 3d subshell to achieve a more stable electron configuration.
[Ar] 4s2
Noble gas notation is a way of simplifying electron configurations by using the previous noble gas's electron configuration as a starting point. For calcium, the electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2. Using the noble gas argon (1s2 2s2 2p6 3s2 3p6) as the starting point, the noble gas notation for calcium is [Ar] 4s2.
The electron configuration for a calcium atom with atomic number 20 is 1s2 2s2 2p6 3s2 3p6 4s2. This can be represented using the noble gas shorthand notation as [Ar] 4s2, where [Ar] represents the electron configuration of argon.
The noble gas core notation for Calcium is [Ar]4s2. This notation represents the electron configuration of Calcium by using the nearest noble gas (Argon) as a reference.

Neutral calcium has 20 protons and 20 electrons. The first 20 atomic orbitals are filled as 1s2 2s2 2p6 3s2 3p6 4s2. The shorthand for this is [Ar] 4s2 since argon's configuration is 1s2 2s2 2p6 3s2 3p6.
Neutral calcium's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. Ca2+ is the ion of calcium, which means that it has 2 less electrons than neutral calcium. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6.
The electron configuration for calcium is 1s2 2s2 2p6 3s2 3p6 4s2. Calcium has 20 electrons, so it fills the 4s subshell before the 3d subshell to achieve a more stable electron configuration.
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
Considering the normal calcium ion Ca2+ it has the same electronic configuration as the noble gas Argon.
Calcium has two valence electrons, both of which are unpaired. •Ca•
The electron configuration of calcium in its ground state is 1s2 2s2 2p6 3s2 3p6 4s2. In its excited state, one or more electrons transition to higher energy levels. For example, one possible excited state electron configuration for calcium could be 1s2 2s2 2p6 3s2 3p6 4s1 3d1.
