Electron configuration of Calcium ^+2

The electron configuration of calcium in its neutral state is 1s2 2s2 2p6 3s2 3p6 4s2.

When calcium loses two electrons to become Ca+2, the two electrons are removed from the highest energy level, which is the 4s orbital.

Therefore, the electron configuration of Ca+2 is 1s2 2s2 2p6 3s2 3p6.

To determine the electron configuration of a calcium ion with a +2 charge (Ca^2+), we will need to remove two electrons from the neutral atom of calcium.

The atomic number of calcium is 20, meaning it has 20 electrons. The electron configuration of the neutral calcium atom is:

1s^2 2s^2 2p^6 3s^2 3p^6 4s^2

To remove two electrons, we will remove them from the 4s orbital. Thus, the electron configuration of the calcium ion (Ca^2+) is:

1s^2 2s^2 2p^6 3s^2 3p^6

To determine the electron configuration of a Calcium ion with a charge of +2 (Ca^+2), we first need to know the electron configuration of a neutral Calcium atom.

The atomic number of Calcium (Ca) is 20, meaning it has 20 electrons in its neutral state. The electron configuration of a neutral Calcium atom can be determined by using the Aufbau principle and the periodic table.

The Aufbau principle states that electrons occupy the lowest energy level available first. In other words, electrons fill up orbitals in a specific order.

To determine the electron configuration of Calcium (Ca), we follow this order:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s².

Now, for Calcium ion with a charge of +2 (Ca^+2), we need to remove two electrons from the neutral atom. Since electrons are removed from the highest energy level first, we remove them from the 4s orbital.

Therefore, the electron configuration of Calcium ^+2 (Ca^+2) can be written as:

1s² 2s² 2p⁶ 3s² 3p⁶.

Note that the 4s orbital is completely empty in the Calcium ^+2 ion.
