The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
Because each of them can form a cation with the electron configuration of a noble gas by donating one electron to another element.
