Oh, isn't that just a happy little question! Strontium fluoride has the noble gas electron configuration of krypton, which is [Kr]. This means it has a stable electron configuration similar to a noble gas, making it less likely to react with other elements. Just like painting a serene landscape, understanding electron configurations can bring a sense of peace and harmony to your chemistry studies.
The noble gas configuration for Sr (strontium) is [Kr]5s2
Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton. Strontium has 38 electrons in its neutral state, while krypton has 36 electrons. By losing 2 electrons, Strontium becomes Sr2+, and its electron configuration is similar to krypton.
The noble gas electron configuration of sodium fluoride is [Ne]3s^1 3p^5. This means that it has the same electron configuration as neon, with an additional 3s^1 electron from sodium and a 3p^5 electron from fluorine.
Neon has the same electron configuration as the Fluoride ion however a spectrum of these although the same will be shifted in wave-length due to the additional charge on the Neon atoms nucelus.
It should lose two electrons

1s2 2s2 2p6 is the electron configuration of the fluoride ion. It has a complete octet and is isoelectronic with neon. Before it becomes an ion, it is 1s2 2s2 2p5 Then it gains an electron and has a negative charge.
Strontium has 38 electrons. It needs to give up 2 electrons to achieve a noble gas electron configuration, similar to the nearest noble gas, which in this case is krypton (36 electrons).
The bipositive ion of strontium takes the electron configuration of xenon.
Neon has the same electron configuration as the Fluoride ion however a spectrum of these although the same will be shifted in wave-length due to the additional charge on the Neon atoms nucelus.
The noble gas element strontium (Sr) has the electron configuration of [Kr]5s^2. This means that it has the same electron configuration as krypton (Kr), with two electrons in its outermost shell (5s).
The noble gas configuration of strontium is [Kr]5s². Strontium has an atomic number of 38, which means it has 38 electrons. The noble gas before strontium is krypton ([Kr]), which has 36 electrons. The remaining two electrons fill the 5s orbital in strontium, leading to the noble gas configuration [Kr]5s².
It should lose two electrons
The electron configuration of a fluorine atom is 1s2 2s2 2p5. When fluorine gains an electron to form a fluoride ion, its electron configuration becomes 1s2 2s2 2p6, which is the same as that of a noble gas (neon). This gives the fluoride ion a stable, filled outer electron shell.
It accepts one electron.
