Answer:
Here's what I get.
Explanation:
The isotopic symbol for an atom is
The atomic number (Z) is the number of protons (p) in the nucleus.
In a neutral atom, the number of electrons (e) equals the number of protons. n = e
The mass number (A) is the number of protons plus the number of neutrons (n).
A = p + n or
n = A - p
(a)
p = 5
e = 5
n = 10 - 5 = 5
(b)
p = 18
e = 18
n = 36 - 18 = 18
(c)
p = 38
e = 38
n = 85 - 38 = 47
(d)
p = 5
e = 6
n = 11 - 6 = 5
