Spectra Let's take a look at something that is slightly more realistic. For life to form, there Identify which elements are has to be a host planet with the right conditions. In addition, more elements are required to build a planet and useful to have a wide diversity of life. Here's a more comprehensive (but still not which elements are required to complete!) list of elements required for both planets and a diversity of life. build life. 2 1 He Building a Planet Build Life H 7 P Ne V Hydrogen (H) Hydrogen (H) Li Be 13 14 17 Ar Helium (He) Helium (He) 71 12 A Si Na Mg 34 135 V Carbon (C) 24 25 26 27 28 29 30 LE 32 V Carbon (C) 20 21 22 23 Ca Ti V Cr Mn Fe Co Ni Cu Zn Ga Ge As Se Br Kr K V Nitrogen (N) 52 Nitrogen (N) 41 42 43 44 45 Xe Rb Sr C 7r Nb Mo TC Ru Rh Pd Ag Cd In Sn Sb Te Oxygen (0) V Oxygen (0) 21 32 24 26 56 75 55 72 Ba Hf Ta W Re Os Ir Pt Au Hg pb Bi Po At Rn C5 V Neon (Ne) Neon (Ne) 110 112 114 115 115 117 118 105 107 108 109 Fr Ra Rf Db Sg Bh HS Mt DS Rg Cn Uut FI Uup Lv Uus Uuo v Sodium (Na) Sodium (Na) Magnesium (Mg) Magnesium (Mg) 61 63 65 65 57 70 71 57 58 59 60 Ce Pr Nd Pm Sm Eu Gd Tb Dy Ho Er Tm Yb Lu la Aluminum (Al) Aluminum (Al) 95 100 101 102 103 92 94 95 Ac Th Pa U Np Pu Am Cm Bk Cf Es Fm Md No Lr V Silicon (Si) Silicon (Si) V Phosphorus (P) V Phosphorus (P) Sulfur (S) v Sulfur (S) Potassium (K) Potassium (K) Calcium (Ca) Calcium (Ca) Iron (Fe) Iron (Fe)
