Answer:
If the charge is positive, subtract that number from the atomic number to get the number of electrons. You have more protons.
...
Determining the number of electrons-
a) 28 Si protons = 14, electrons = 14, neutrons = 14
14
b) 197 Au b p = 79, e = 79, n = 118
79
c) 40 Ar c p = 18, e = 18, n = 22
18
d) 64 Cu d p = 29, e = 29, n = 35
29
e) 39 K e p = 19, e = 19, n = 20
19
f) 133 Cs f p = 55, e = 55, n = 78
55
