As
400
Draw the Lewis Dot Diagram for oxygen
500
Explain why fluorine has a smaller atomic radius than chlorine.
Fluorine has fewer electron shells than chlorine
500
Arrange the following elements in order of increasing ionization energy; Al, Na and S.
Na, Al, and S
500
Why are noble gases chemically stable?
They have full shell of 8 VE
500
What's the difference between a group and a period? What information can we get from them?
Groups are the vertical columns on the periodic table, periods are the horizontal rows.
Groups tell us the number of valence electrons, periods tell us how many energy levels are used to arrange the electrons.
