HideShow resource information
What are the rings of electrons around an atom's nucleus called?
Electron shells / Energy levels
1 of 9
How many electrons can the lowest energy level hold?
2 electrons
2 of 9

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
