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 the number of valence electrons for elements in Group 6A (also known as Group 16), we need to look at the periodic table.
Step 1: Locate Group 6A on the periodic table. Group 6A is located on the right side of the periodic table, second to last column.
Step 2: Identify the elements in Group 6A. The elements in Group 6A include oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po).
Step 3: Determine the number of valence electrons for each element in Group 6A. Valence electrons are the electrons present in the outermost energy level of an atom. In Group 6A, the number of valence electrons remains the same for each element, which is 6.
Therefore, the answer to the question is C. The number of valence electrons remains the same as one descends Group 6A of the periodic table.
