Solution
Zirconium-90 is an isotope of zirconium. The number after the element name (90 in this case) is the atomic mass number, which is the sum of protons and neutrons in the nucleus.
-
The atomic number of zirconium is 40, which means it has 40 protons.
-
In a neutral atom, the number of protons is equal to the number of electrons. So, zirconium also has 40 electrons.
-
To find the number of neutrons, you subtract the number of protons from the atomic mass number. So, 90 (atomic mass number) - 40 (number of protons) = 50 neutrons.
So, the correct answer is 40 protons, 40 electrons, and 50 neutrons.
