QUESTION:
How many neutrons are in an atom with each atomic number and mass number?
(a) Z = 28, A = 59
(b) Z = 92, A = 235
(c) Z = 21, A = 46
(d) Z = 18, A = 42
ANSWER:
Step 1 of 2
To determine the number of neutrons in an atom, one must know its atomic number (Z), representing the number of protons, and its mass number (A), which is the combined number of protons and neutrons. By subtracting the atomic number from the mass number, the count of neutrons can be deduced.
(a) For an element with Z = 28 and A = 58, it is Nickel. Calculating 58 minus 28 yields 30, denoting 30 neutrons in Nickel.
