In a group,the ionization energy decreases because the atomic size increases(no. of shells increases, therefore due to this, there's a weak attractive force between nucleus and the valence electrons)
Answer:
33 Neutrons
Explanation:
Atomic Mass = # of Protons + # of Neutrons
Atomic Number = Proton count
Atomic Mass of Co = 27 Protons + x Neutrons
60 = 27 + x
x = 33
