## Step 1The problem is asking us to identify an element based on its electron configuration. The electron configuration of an element is determined by the number of valence electrons and the number of energy levels it has.## Step 2Valence electrons are the electrons in the outermost shell of an atom. They are the electrons that participate in chemical bonding. In this case, the element has 3 valence electrons.## Step 3Energy levels, also known as shells, are the regions around the nucleus of an atom where electrons are located. The number of energy levels an element has can be determined by the number of electron shells it has. In this case, the element has 3 energy levels.## Step 4By combining the information from steps 2 and 3, we can conclude that the element is Boron (B). Boron has 3 valence electrons and 3 energy levels.
