Verified step by step guidance1
Understand that the atomic number of an element corresponds to the number of protons in its nucleus. Each element on the periodic table has a unique atomic number.
Recall or refer to the periodic table to find the element with atomic number 52. The atomic numbers increase sequentially from hydrogen (1) upwards.
Locate the element with atomic number 52 on the periodic table. This element is positioned in the p-block and is a metalloid.
Identify the symbol and name of the element with atomic number 52. This element is known as tellurium, with the symbol Te.
Confirm that the other options (I, Sb, Xe) correspond to different atomic numbers: Iodine (I) is 53, Antimony (Sb) is 51, and Xenon (Xe) is 54, so they do not match atomic number 52.
