Electron shells / Energy levels 1 of 9 How many electrons can the lowest energy level hold? 2 electrons 2 of 9 How many electrons can each energy level after the first one hold? 8 electrons 3 of 9 Neon has 10 electrons. What is its electronic structure? 2,8 (2 electrons in the first shell, then 8 in the second) 4 of 9 Sodium has 11 electrons. What is its electronic structure? 2,8,1 (2 electrons in the first shell, 8 in the second, and one in the third) 5 of 9 How many electrons are in the outermost shell of all group 1 elements? 1 electron 6 of 9 Which group on the periodic table has 7 electrons in the outermost shell of all its elements? Group 7 7 of 9 Which group are the elements lithium, sodium and potassium in? Group 1 8 of 9 Which group has the most stable electronic structures? Why? Group 0 - the outermost shells are full so they don't react 9 of 9
