Final answer:
The information found in an element's box in the periodic table includes the atomic number and chemical symbol of the element. The correct answer is option B.
Step-by-step explanation:
In the periodic table, the information found in an element's box includes the atomic number and the chemical symbol of the element. The atomic number represents the number of protons in an element's nucleus and is unique to each element.
It is displayed above the element's symbol in the periodic table. The chemical symbol is a one- or two-letter abbreviation used to represent the element. It is displayed in the box along with the element's name, atomic number, and atomic mass.
The chemical symbol, consisting of one or two letters with only the first being capitalized, represents the name of the element and is typically found in the center of the box.
