Mini Quiz- Half Sheet H = 1.01 g/ mol , O = 16.00 g/ mol S = 32.07 g/ mol , N = 14.01 g/ mol , I = 126.90 g/ mol. How many grams in 3.4 x 10 23 molecules of H 2 SO 4 ? 2. How many molecules are there in 0.40 g of N 2 I 6 ?. Nuclear Chemistry. Unstable Nuclei.
2. How many molecules are there in 0.40 g of N2I6?
Often nuclei of very large atoms are unstable…
Unstable Nuclei Stable Nuclei + Energy
A p+ to no ratio that is not close to 1:1
Example: Polonium (Po) has 84 protons and 125 neutrons
Oxygen has 8 protons and 8 neutrons
212-4 = 208 mass of new element
84-2 = 82 atomic number of new element
