For instance, the ground state electronic configuration of calcium (z=20) is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2.

Electron configuration of calcium in ground state. Since we need to take away two electrons, we first remove electrons from the outermost shell (n=4). They deviate from the general rule only by last 2 to 3 electron positions. The electron configuration for calcium is:

1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 1. Calcium atoms have 20 electrons and the shell structure is 2.8.8.2. A calcium 2+ ion has lost its two valence electrons, and now has 18 electrons.

1s 2 2s 2 2p 6 3s 2 3p 6 4s 2. The ground state electron configuration. Hence, the electron configuration for ca 2+ is 1s 2 2s 2 2p 6 3s 2 3p 6.

Since 1s can only hold two electrons the next 2 electrons for calcium go in the 2s orbital. Normally, ca has the configuration of [ar]4s 2. 1s^2 2s^2 2p^6 3s^2 3p^6 , which is isoelectronic with the noble gas argon.

Since we need to take away two electrons, we first remove electrons from the outermost shell (n=4). The calcium ion (ca 2+), however, has two electrons less. Scandium atom ground state electron configuration.

The total number of occupied principle energy levels in this atom is a. Atomic number of calcium is 20. In writing the electron configuration for calcium the first two electrons will go in the 1s orbital.
