PPT-Lecture 2.2 Atomic Models

We now have much evidence that an atom is made of a nucleus and electrons orbiting around the nucleus What did people think before Even back in the days of Plato and Aristotle people were debating whether or not matter could be cut in half indefinitely. Bell Ringer . Review..Frame. your argument. Bell Ringer: What was the name of the program to build the Atomic Bomb? Who was the lead scientist?. Agenda: Notes/discussion. Objective: Through Discussion and notes students will begin to understands the steps leading to the dropping of the atomic bomb.. Qubits. . "Ultrafast Gates for Single Atomic Qubits," . W. C.

Virus assembly. Structure is a key element in understanding viral assembly. X-Ray crystallography can resolve atomic structural information, so why not use it?. #1: Rubidium has two common isotopes, . 85. Rb and . 87. Rb. . If the abundance of . 85. Rb is 72.2% and the abundance of . 87. Rb is 27.8%, what is the average atomic mass of rubidium?. PROCEDURE:. by . Tiffany, Katelyn, Veronica, . Kole. John Dalton (1766-1844). John Dalton was born into a Quaker Family.. Born: September 6. th. , 1766 in Cumberland, England. He was an English . Meteorologist and then. Chemistry. Learning Goals . To be able to . explain and draw atomic structure. Elements. Elements are the . building blocks. of all . matter. on Earth. Elements are made up of . atoms. Differences in . 1.c. – Students know how to use the periodic table to identify alkali metals, alkaline earth metals and transition metals, trends in ionization energy, electronegativity, and the relative sizes of ions and atoms..

Chapter 1D. Warm Up November . 28. What is smaller, an atom or a cell? . Name and describe one element that you are familiar with on the periodic table. . When large blooms of algae die, decomposers use all the oxygen in the water to break down the dead algae. What is this a result of? . You are to invent your own superhero from and element that you choose. Your superhero must have superpowers that tie into the properties and characteristics of the element that you choose. . Use your book . All atoms of an element have the same number of protons and the same atomic number.. Learning Goal . Given the atomic number and the mass number of an atom, state the number of protons, neutrons, and electrons.. Science is based off of observations.. A Scientific Law is a summary of what is seen in observations. . A Scientific Theory is an explanation of why these observations are occurring.. Both laws and theories are tested by using them to predict what would happen in certain situations.. Matter describes anything that has . mass. and . volume. Can matter be invisible? . YES. Ex. .
