PPT-Electrons in Atoms

Chapter 5 The scale model shown is a physical model However not all models are physical In fact several theoretical models of the atom have been developed over the last few hundred years You will learn about the currently accepted model of how electrons behave in atoms. Physical Science. Chapter 4 – Section 2. State Standards. CLE.3202.1.2 – Describe the structure and arrangement of atomic particles. What is an Atom?. The three main components of an atom are . distinquished. Physical Science. Chapter 4 – Section 2. State Standards. CLE.3202.1.2 – Describe the structure and arrangement of atomic particles. What is an Atom?. The three main components of an atom are . distinquished. At the end of this lesson, you need to draw . a diagram for each model showing the evolution of atomic theory:. ". Plum-Pudding" Model. Rutherford . Atom. Rutherford-Bohr . Atom. Charge-Cloud . Model. . and . Periodic Table. Antoine Lavoisier. Law of Conservation of Matter: matter can not be destroyed nor created.. Dalton’s Atomic Theory. All elements are composed of atoms.. Atoms of the same element are identical. Atoms of any one element are different than atoms of another element.. Chapter 2 BLB 12. th. Expectations. Recognize important steps in the discovery of the atom and its structure.. Work with isotopes.. Learn about the periodic table.. Differentiate between molecular and ionic compounds.. Valence Electrons and Bonding. The number of valence electrons (electrons in the outermost energy level) in an atom of an element determines many properties of that element, including the ways in which the atom can bond with other atoms..

Lesson Objectives. Appreciate that there are various models to illustrate atomic structure. Know that early models of atomic structure predicted that atoms and ions with noble gas electron arrangements should be stable. Nursing students. Chapter 1. Introduction into organic chemistry .

How is an atom’s mass calculated? . Which subatomic particles are electrically charged?. .. Essential Questions:. 4. Where are the three main subatomic particles located?. Atoms are composed of protons, neutrons and electrons. These subatomic particles are charged….. Atoms make elements… Elements can’t be broken down into anything simpler. . Examples:. Carbon= C. Atoms and the Periodic Table Atomic Structure ATOM: the smallest particle that has the properties of an element. From the early Greek concept of the atom to the modern atomic theory, scientists have built on and modified existing models of the atom.
