Answer 1

Answer:

b)Ti4+ c

MARK ME AS BRAINLIEST.

Answer 2

NONE OF THE GIVEN OPTIONS WILL HAVE d s CONFIGURATION.

Explanation:

• The first transition series have a general electronic configuration of $[Ar]3d^{1-10} 4s^{2}$.
• The electronic configuration of Scandium is $[Ar]3d^{1} 4s^{2}$.
• The electronic configuration of titanium is $[Ar]3d^{2} 4s^{2}$.
• The electronic configuration of vanadium is $[Ar]3d^{3} 4s^{2}$.
• When they lose electrons, first the electrons are removed from 4s orbital, then from 3d orbital.
• Scandium will lose 3 electrons, titanium 4 electrons, vanadium 5 electrons and  and its configuration will become equal to that of argon.
• $Sc^{3+}=[Ar]\\Ti^{4+}=[Ar]\\V^{5+}=[Ar]$
• Therefore, none of the given species will have d s configuration.
