Identify the atomic number of the element tellurium (Te). The atomic number is given as 52.
Recall that the atomic number of an element represents the number of protons in one atom of that element.
Since the atom is neutral, the number of protons equals the number of electrons, but for this question, focus on protons only.
Therefore, the number of protons in one neutral atom of tellurium is equal to its atomic number, which is 52.
No further calculation is needed; the answer is simply the atomic number.
