Please help me, I really need it, God Bless you <3

Answer 1

#1

`\\ \sf\longmapsto {}^(88)_(38)Sr^(2+)`

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

#2

`\\ \sf\longmapsto {}^(51)_(23)V^(3+)`

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

#3

`\\ \sf\longmapsto {}^(55)_(26)Fe^(3+)`

• No of neutrons=55-26=29

#4

`\\ \sf\longmapsto {}^(112)_(48)`

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

#5

`\\ \sf\longmapsto {}^(210)_(82)Pb^(2+)`

• No of neutrons=210-82=128
