1 Categories of Earth’s Materials • Minerals • Metals • Rocks • Melts • Glasses • Organics • Volatiles ? Question of the Day ? I’ve made the point that Stars are element factories, and that elements like H and He can be created in Stars like our Sun, heavier elements to Fe in stars much larger than our Sun, whereas, elements heavier than Fe require the immense pressure / energy of a Supernova. Question: Are there other processes in which certain elements can be created anywhere (naturally, not in a laboratory), including right here on Earth? If so, how? Question 1 A toms that have the same number of protons but a different number of electrons are called ______. A) isotopes B) isomeres C) ions D) atoms Question 2 An ion is an atom or molecule which has lost or gained one or more electrons, making it positively or negatively charged. An ion that has fewer electrons in its electron shells than it has protons in its nuclei , is positively charged and is known as ________. A) Isotope B) Cation C) Onion D) Anion Question 3 An ion is an atom or molecule which has lost or gained one or more electrons, making it positively or negatively charged. Conversely, an ion that has more electrons in its electron shells than it has protons in its nuclei , is negatively charged and is known as ________. A) Isotope B) Cation C) Onion D) Anion Question 4 A toms that have the same number of protons but different number of neutrons in their nucleus are called ________. A) Cations B) Isotopes C) Anions D) Isomeres
