Answer 1

no. of neutrons = mass no. - atomic no

=> 65-30 = 35

hence number of neutrons in dipositive zinc Ion with mass number 65 equals to 35

Answer 2

Heya mate!!!

Please do tap the crown over my answer after reading it if it helps you!I am helping you please help back.....

mass of protons + mass of neutrons = 65.

as no of protons = atomic no. = 30

no. of neutrons = 65 – 30 = 35.
