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 (Sr) typically loses two electrons to form a stable 2+ ion. It belongs to group 2 of the periodic table, which means it has 2 valence electrons that it tends to lose to achieve a full outer shell.
5s orbital
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.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.

Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
Sulfur can both gain and lose electrons when forming ions. It can gain two electrons to form a sulfide ion (S2-) or lose two electrons to form a sulfide ion (S2+).
Strontium lose electrons.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
In reactions, strontium tends to lose electrons because it is a metal. It is in Group 2 of the periodic table, which means it has 2 valence electrons and readily gives them up to achieve a stable configuration.
Strontium typically loses electrons in a chemical change because it belongs to Group 2 of the periodic table, which contains elements that tend to lose two electrons to achieve a stable electron configuration.
Beryllium would tend to lose its two electrons when forming a bond because it is easier to lose its two valence electrons rather than gain an additional five in order to obtain a full outer shell.
