It will lose 2 to form Sr2+
Strontium, element with atomic number 38, will lose 2 electrons to form a stable ion as it tends to lose electrons to attain a noble gas configuration.
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.
It should lose two electrons
Strontium seeks to lose two electrons when it ionizes. This is because it is an alkaline earth metal located in Group 2 of the periodic table, which has two valence electrons. By losing these two electrons, strontium achieves a stable electron configuration similar to that of noble gases.
