The shorthand electron configuration of magnesium is [Ne]3sĀ².
The element with electronic configuration Ar 3d10 4s2 is Calcium (Ca) with atomic number 20.
In the electron dot diagram for calcium, there are two dots shown, as calcium has two valence electrons.
The electron configuration for neutral calcium is 1s2 2s2 2p6 3s2 3p6 4s2. When calcium forms a +2 ion, it loses the two electrons in the 4s subshell, so the electron configuration becomes 1s2 2s2 2p6 3s2 3p6.
The electron would be removed from the outermost energy level, which is the fourth energy level, for calcium.
2, 8 is the electron configuration
The shorthand electron configuration of magnesium is [Ne]3sĀ².
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.
You don't. Calcium is not an electron, calcium is a element
The element with electronic configuration Ar 3d10 4s2 is Calcium (Ca) with atomic number 20.
It is [Ne] 3S2.
[Kr] 5s2
The electron configuration for nitrogen is written as 1s2 2s2 2p3.
2.3!<-----wrong shorthand electron configuration for Boron (B on the periodic table) is [He] 2s2 2p1 because Shorthand means building on the last noble gas element. So put the closest Noble gas element before this one and then the new addition.
The shorthand electron configuration of aluminum is [Ne] 3s^2 3p^1, where [Ne] represents the electron configuration of the noble gas neon. This shorthand notation is used to show the core electrons before the valence electrons in the electronic configuration of an element.
The electron configuration for Hf using noble gas shorthand is [Xe] 6s2 4f14 5d2. The noble gas shorthand represents the electron configuration of the noble gas xenon, which has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.
It is [Ar] 3d1 4s2
