What is the study of matter and the changes it | 10 One Lof lead in one milliliter of water would undergoes? give a 1 ppm solution An atom that loses an electron becomes a There are 10 mg er in each centimeter 8. 1000 grams is the same as one gram What has mass and occupies space? valorum If all measured values are near one another, but the 5. All radiation travels at the speed of light average of these values is not near the actual true 7. Nearly all of the weight of an atom is in the value, the measured values are 10. Electromagnetic radiation has higher energy if the 11. The Pauli principle says that each atomic is shorter orbital can contain two electrons at most 11. Best school in Kentucky 12. This principle is German for "building-up" and means 14. These electrons are nearest the surface of the atom so that electrons under normal conditions will be in the they are the first to interact with electrons from other atoms. lowest energy levels rather than higher energy levels 15. The element with a neon core of electrons, 2 electrons || 13This particle has energy but essentially no massa in the 3s orbital and 4 electrons in 3p type orbitals is 17. The scientific process involves observing some 16. Which atom has 7 protons and 8 neutrons? phenomena, formulating a question about what you 18.
