As one descends group 6A of the periodic table, the number of valence electrons
found in
each element
A. Increases
B. Decreases
C. Remains the same
To determine how the number of valence electrons changes as one descends group 6A of the periodic table, we need to understand the periodic trends in valence electrons.
Group 6A of the periodic table is also known as Group 16 or the oxygen group. This group contains elements such as oxygen (O), sulfur (S), selenium (Se), and tellurium (Te).
Valence electrons are the electrons in the outermost energy level of an atom, specifically the s and p orbitals. In group 6A, the elements have six valence electrons because they are in the sixth column of the periodic table.
As you move down the group, with each successive element, the number of valence electrons remains the same. Therefore, the correct answer is:
C. Remains the same
