3. ionization energy – the energy required to remove an electron from the (gaseous) atom Na + ionization energy Na + + e - first ionization energy for the elements in the first four periods • ionization energy in Group A elements decreases from top to bottom • ionization energy gradually increases from left 4 to right across a period
11.2 Lewis structures of atoms metals tend to form cations and nonmetals tend to form anions in order to attain a stable valence electron structure which contains 8 electrons this rearrangements are accomplished by losing, gaining or sharing electrons with other atoms Lewis structure – using the symbol for element and dots for valence electrons paired dots represent paired electrons unpaired dots represent unpaired electrons ex. · unpaired electron :B paired electron symbol for element Lewis structures for the first 20 elements 5
