What is the number of protons neutrons and electrons in an atom of zirconium 90 that has overall charge and an atomic number of 40?
Zirconium-90 (90Zr) has the atomic number 40, and it has 40 protons. The question asked about a specific isotope of zirconium, and the 90 in this isotope represents the number of protons plus the number of neutrons in 90Zr. The math is simple, and 90 minus 40 tells us there are 50 neutrons in this atom. As the atom was said to be electrically neutral, so that means the number of electrons will be equal to the number of protons. The atom will, therefore, have 40 electrons.
