No. There are five peaks for five electrons. The five electrons can be found as element #5, Boron.


No. There are five peaks but one is much taller than the other. The taller peak represents two electrons so this must be carbon.


Yes. There are five peaks of varying size. The medium sized peaks represent two electrons each. The small peak at the end must be only one electron, while the tallest peak represents six electrons. That is thirteen electrons in total, which is aluminum.


The graph has nothing to do with aluminum. In fact, the x-axis is labeled incorrectly, so this would not represent any one element.
