Answer 1

Since Zn (Zinc ) has atomic number of 30

and atomic number symbolise the number of protons in the atom and

number of electrons in neutral atom = no. Of protons ,

so no. Of protons in Zn+2 = 30

No. Of electrons in Zn+2 = 28

Similarly atomic number of Se ( Selenium ) is 34

number of protons in Se^-2 = 34

Number of electrons in Se^-2 = 36
