The correct order of decreasing second ionization enthalpy of is:( Ti = 22, V = 23, Cr = 24, Mn = 25)(A) Mn > Cr > Ti > V(B) Ti > V > Cr > Mn(C) Cr > Mn > V > Ti(D) V > Mn > Cr > Ti
1 AnswersThe second ionization enthalpy generally increases across a period (from left to right) in the periodic table because as you move across a period, the number of protons in the nucleus increases, leading to a stronger attraction between the nucleus and the electrons. This makes it harder to remove a second electron.
The elements you've listed (Ti, V, Cr, Mn) are all in the same period (period 4) of the periodic table. Therefore, we need to consider their atomic numbers to determine the correct order of decreasing second ionization enthalpy.
Ti (22) < V (23) < Cr (24) < Mn (25)
So, the correct order of decreasing second ionization enthalpy is:
(B) Ti > V > Cr > Mn
