Answer:

40

Explanation:

Zirconium is the 40th element in the periodic table. It means its atomic number (the number of protons inside the nucleus) is 40. But atoms are electrically neutral: this means that their number of electrons matches the number of protons. Therefore, since the atom of zirconium has 40 protons, it also has 40 electrons.
