Question	Answer
Dot Diagrams	the symbol for the element in the center, surrounded by dots indicating the number of valence electrons.
atoms with 4 or fewer valence electrons will lose them to form positive ions	atoms with 5 or more valence electrons will gain enough to have 8
step 1: F	write the electron configuration 1s^2 2s^2 2p^5
step 2: F	decide if it gains or loses an electron F has 7 valence electrons so it will gain 1 electron. the ion formed is F -1
step 3: F	use dots to represent the valence electrons Image: Image009[1] (binary/octet-stream)
dot diagram of a positive ion	there will be no dots on this diagram
dot diagrams of negative ions	an x will be used to place the remaining dots
