Guida verificata passo dopo passo1
Understand that the atomic number of an element is the number of protons in the nucleus of an atom of that element.
Recall that the atomic number uniquely identifies an element on the periodic table.
Locate zirconium (Zr) on the periodic table to find its atomic number.
Note that zirconium is in period 5 and group 4 of the periodic table.
Confirm that the atomic number of zirconium (Zr) is 40, meaning it has 40 protons.
