Lesson 1 Key Questions 1. Mg2+ has 10 electrons 2. Given that the half life of the radioisotope carbon -14 is 5730 years‚ it would not be useful in dating bones that are over a million years old. After 40 000 years of age less than 1% of the 14C is left in the bone and thus it is not useful for determining the exact age beyond that. 3. Hydrolysis - A chemical reaction where a chemical is broken down by a reaction with water. Hydrolysis is important for the digestion of food‚ making

Democritus was an Ancient Greek pre-Socratic philosopher of Ancient Greece. He along with Leucippus were atomic theorists who proposed during the fifth century B.C that 1. Matter is composed of atoms separated by empty space by which atoms move. 2.Atoms are solid‚ homogeneous‚ indivisible‚ and unchanging. Democritus knew that if he took a rock and chisel it in half‚ that both halves would characteristically have the same properties as the whole. He rationalized that if he was to continue to cut the
