Consider the image below which represents an individual block on the periodic table.  Answer the following questions with the appropriate letter from the list given below.

-What does the "X" represent?

Quizplus · Accepted Answer

The "X" in the block represents the chemical symbol of the element, which is typically a one or two letter abbreviation for the name of the element.

Answer: A
 The atomic number of an element is the number of protons in the nucleus of an atom of that element. It is represented by the whole number above the chemical symbol in the block. The other options are not represented by the "X" in the block.

Note: The atomic weight is typically listed below the chemical symbol in the block, but it is not represented by the "X." The mass number is the sum of the number of protons and neutrons in the nucleus of an atom of that element, but it is not represented by the "X" either. The chemical name is the full name of the element, but it is not typically included in the block.
