question 2 of 10
what does the number above the symbol represent?
a. the ionic number
b. the isotope number
c. the atomic number
d. the atomic mass

Explanation:

In chemistry, when looking at an element's symbol in the periodic table, the number above the symbol represents the atomic number. The atomic number is defined as the number of protons in an atom of that element. It is a fundamental property used to identify and classify elements. The ionic number is related to the charge of an ion. The isotope number is not a standard term in this context. The atomic mass is usually the number below the symbol (average mass of isotopes).

Answer:

C. The atomic number
