![]() ![]() Group 1 has 1 valence electron, Group 2 has 2 VE.….etc. The group number of a main group element tells us the number of valence electrons. When done, count the electrons in the outer shell. Remember: The number of protons is equal to the atomic number. Since the element is not carrying a charge, there are equal numbers of protons and electrons. Valence electrons are the only electrons used in chemical bonds. It is the number of valence electrons that will determine the chemical properties of the element. Valence electrons are the electrons in the highest occupied energy level of an atom. Second, determine the number of valence electrons Draw the appropriate number of dots around the symbol making sure to put one dot on each side before putting a second dot.
