Portions of electromagnetic waves A, B, and C are represented below (not drawn to scale): Rank them in order of (a) increasing frequency; (b) increasing energy; (c) increasing amplitude. (d) If wave B just barely fails to cause a current when shining on a metal, is wave A or C more likely to do so? (e) If wave B represents visible radiation, is wave A or C more likely to be IR radiation?
Chemistry Week 4 Notes: 2.3Units of Measure: Memorize metric Prefixes (Ten Grey Mountain Kats – My Mom knits Pelts) Anything that is defined is an exact number “1” goes with the prefix 3.1Molecules in Chemistry A molecule is a specific number and kind of atoms held in a specific arrangement that cannot be broken down without creating a different substance (physical change) Molecules are made from element sharing electrons (compounds are made from nonmetals and semi metals only) How are molecules formed electrons share electrons with other elements Example: Some elements exist as moleculesdiatomic elements o gases at room temp H ,N ,O F Cl
