  1. Alien Element Clue What did you learn ? Bo, Wo, J, L They are noble gases Noble gases are in group 18 Bo, Wo, J, L Wo has greatest atomic mass, Bo the least The atomic mass of the elements increases as you move left to right and top to bottom on the Per. Table

  2. Alien Element Clue What did you learn ? X, By, Ch, Q They are the most reactive group Reactivity decreases as you move from left to right on the Per. Table A, V, Kt Non-metals who typically gain or share one electron -Atoms can gain or lose electrons -The # of electrons an atom will gain, lose or share is determined by the group that it is in.

  3. Alien Element Clue What did you learn ? E, Hi, T, Ss They are metalloids Metalloids are located between the metals and the non-metals along the zigzag line. T T has more protons than Hi The number of protons is equal to the atomic #

  4. Alien Element Clue What did you learn ? Pf, El Pf is the lightest element, El is the heaviest The atomic mass (lightness or heaviness) increases as you move left to right and down the periodic table Kt and By Kt and By make table salt Table salt is made of NaCl

  5. Alien Element Clue What did you learn ? Do Do has 4 protons The number of protons is equal to the atomic number on the periodic table Fx Fx is important in the chemistry of life Carbon is important in the chemistry of life

  6. Alien Element Clue What did you learn ? R, Do R is less reactive than Do The further to the right you move on the periodic table, the less reactive the element is M, G, Ss G has less electrons than M As you move across the periodic table from left to right, the number of electrons increases in each period

  7. Alien Element Clue What did you learn ? Up, Oz, Nu They all gain 2 electrons Elements on the right side of the periodic table gain electrons (except for the noble gases) Nu It’s a diatomic molecule Diatomic = 2 atoms hanging out together. Oxygen hangs our as O2

  8. Alien Element Clue What did you learn ? An An has 49 electrons The number of electrons = the atomic number Z, Pi They lose 2 electrons Atoms on the left side of the periodic table tend to lose electrons

  9. Alien Element Clue What did you learn ? Z Z is used in flash bulbs Mg is used in flashbulbs
