What does the Lewis symbol for an element represent?
-
A.
The number of protons in an atom
-
B.
The total number of electrons in an atom
-
C.
The atomic mass of an element
-
D.
The valence electrons of an atom
Correct Answer:
D. The valence electrons of an atom
Explanation:
Lewis symbols, also known as Lewis dot diagrams, are used to visualize the valence electrons of an atom. These diagrams consist of the element's chemical symbol surrounded by dots, where each dot represents one electron in the outermost shell. While the total number of electrons or protons determines an element's identity and atomic mass, only the valence electrons are depicted because they are primarily responsible for the atom's chemical bonding behavior.
