  1. Chapter 6 Periodic Table Periodic Trends

  2. Atomic number Electrons in each energy level Na 2 8 1 11 Element symbol Sodium Element Name 22.990 Average atomic mass

  3. Metals Metalloids Nonmetals

  4. good conductors of heat and electricity - ductile • high luster - malleable • mostly solids at room temperature Metals

  5. poor conductors of heat and electricity • brittle • mostly gases at room temperature Nonmetals

  6. semi-conductors • characteristics of metals and nonmetals Metalloids

  22. s-block p-block d-block f-block s1 p6

  23. Electron Configurations in Groups Noble Gases (Group 18) - configuration ends in s2p6 Representative Elements (s- and p-blocks) - s-block configurations end in s1-2 - p-block configurations end in s2p1-6

  24. Atomic Size • Atomic radius is one half of the distance between the nuclei of two atoms of the same element when the atoms are joined • The attractive force of the nucleus decreases as one moves left across a period • The number of shells (energy levels) increases as one moves down a group

  25. Atomic Size Increases Increases

  26. Atomic Size Which element has the largest atomic radius? Francium

  27. Ionic Size • Neutral atoms have equal numbers of protons and electrons • Ions have a positive or negative charge • Cation • An atom or group of atoms with a positive charge • Anion • An atom or group of atoms with a negative charge

  28. Ionic Size • Cations are always smaller than the atoms from which they form • Anions are always larger than the atoms from which they form e- e- 11 p+ 11 p+ 11 e- 10 e- 17 p+ 17 p+ 17 e- 18 e-

  29. Ionization Energy • Ionization energy  the energy required to remove an electron from an atom • Every element wants to gain or lose electrons to act like a Noble Gas

  30. Ionization Energy Increases Increases

  31. Electronegativity • Electronegativity is the ability of an atom of an element to attract electrons when the atom is in a compound • Remember that every element wants to act like a Noble Gas

  32. Electronegativity Increases Increases
