Valence electrons are the lectrons present in the outermost shell of the element. they are involved in bonding with the other atom.
The electronic configuration of tin, krypton and strontium and titanium and their valence electrons are as follows:
[Kr] 4d10 5s2 5p2
Valence electrons in titanium are 4 which are present in the outermost fifth orbital.
[Ar] 3d10 4s2 4p6
Valence electrons in krypton are 8 which makes its very stable.
Strontium has 2 valence electrons.
[Ar] 3d2 4s2
Titanium has 4 valence electrons.
