Strontium has 4 valence electrons.
Two valence electrons
No, Strontium is an alkaline earth metal which exists in solid state.

An isotope has extra or fewer neutrons in the nucleus than the average number for that element. This may or may not result in a radioactive isotope. An ion has extra or fewer electrons orbiting the nucleus. This usually increases the chemical reactivity.
Strontium is located in group 2 of the periodic table. Hence it has two valence electrons. The oxidation number atomic strontium is 0 where that of strontium ion is +2.
Strontium has 4 valence electrons.
There are 2 valence electrons in Radium. There are 2 valence electrons in Radium.
Two valence electrons
No, Strontium is an alkaline earth metal which exists in solid state.

. Sr .There should be two valence electrons around the element since Strontium is in the second column of the Periodic Table and has two valence electrons filling the 5s shell.
An isotope has extra or fewer neutrons in the nucleus than the average number for that element. This may or may not result in a radioactive isotope. An ion has extra or fewer electrons orbiting the nucleus. This usually increases the chemical reactivity.
All alkali earth metals have two valence electrons and they all form ions in +II oxidation state.
Strontium has 38 electrons. (Protons and electrons are the same)
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.
Strontium is part of Group IIA, which means it loses 2 valence electrons to satisfy the rule. Sr2+.
