$\\ \sf\longmapsto {}^{88}_{38}Sr^{2+}$

As 2 electrons are donated Hence the No of electrons =38-2=36

$\\ \sf\longmapsto {}^{51}_{23}V^{3+}$

As 3 electrons donated the no of electrons=23-3=20

$\\ \sf\longmapsto {}^{55}_{26}Fe^{3+}$

No of neutrons=55-26=29

$\\ \sf\longmapsto {}^{112}_{48}$

As 2 electrons are donated no of electrons =48-2=46

$\\ \sf\longmapsto {}^{210}_{82}Pb^{2+}$

No of neutrons=210-82=128
