Arsenic (As), which is element 33 on the periodic table, has a total of 5 valence electrons. Being in group 15 (or 5A, also known as the nitrogen family), elements in this group typically have 5 valence electrons. This is due to its electron configuration, which shows that arsenic has 5 electrons in its outermost shell.
Use the periodic table to answer the question. How many valence electrons does each atom of arsenic have? Arsenic is element 33. It is in period 4 and family 15 (5A with a nitrogen family)
