Strontium has 4 valence electrons.
Two valence electrons

Strontium typically loses 2 electrons to satisfy the octet rule. Since strontium is in group 2 of the periodic table, it has 2 valence electrons. By losing these two electrons, it attains a stable electron configuration similar to a noble gas.
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.
There are no unpaired electrons in strontium.
There are 2 valence electrons in Radium. There are 2 valence electrons in Radium.

Strontium has 38 electrons. (Protons and electrons are the same)
oxygen has 6 valence electrons as indicated by the 6A above the group oxygen is in
There are no unpaired electrons in strontium.
Strontium's atomic number is 38. So, it has 38 protons and 38 electrons if it's neutral. Strontium is a group 2 element and so has 2 valence electrons. Thus, the rest of the 36 electrons are core electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
