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 answer to this question, we need to understand the periodic table and the patterns it exhibits. In this case, we are concerned with Group 6A of the periodic table, which is commonly known as Group 16.
To find the number of valence electrons in an element, we need to check its position on the periodic table. The valence electrons are the electrons found in the outermost energy level or shell of an atom.
In Group 6A or Group 16, you can find elements such as oxygen (O), sulfur (S), selenium (Se), and tellurium (Te), among others. These elements are located in the p-block and have electrons filling the p-orbital.
As we move down Group 6A, from oxygen to sulfur, selenium, and tellurium, we find that the number of valence electrons remains the same. Elements in the same group have the same number of valence electrons. In Group 6A, all elements have six valence electrons.
So, the correct answer to the question is C. The number of valence electrons remains the same as you descend Group 6A of the periodic table.
