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
