The three main components of an atom are . distinquished. 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.. Atoms, Orbitals & Bonding Topics:. Very quick history of chemistry…. What is organic chemistry?. Atomic models: nuclear to quantum. All . about . orbitals. How . orbitals fill: electron . configuration. If we can’t see the electron, and it has no mass, then why is it important?. BONDING!. Electrons are the only particle that participate in bonding between atoms.. How do we know when and how things will bond, though?. Flame Test . Flame Test. According to Bohr theory of the atom, electrons may occupy only specific energy levels. Electrons in atoms jump from their ground state to excited states by absorbing energy. Eventually these electrons fall back to their ground state, reemitting the absorbed energy in the form of light. Because each atom has a unique structure and arrangement of electrons, each atom emits a unique spectrum of light. This characteristic light is the basis for the chemical test known as a flame test. In this test, being placed within a flame excites the atoms. As they reemit the absorbed energy in the form of light, the color of the flame changes. For most metals, these changes are easily visible. However, even the presence of a tiny speck of another substance can interfere with the identification of the true color of a particular type of atom. . There are about 100 different types of atoms. An element is a substance which contains only one type of atom. Atoms. Atoms. The Periodic Table. The Periodic Table. Element, Compound, Mixture. Element, Compound, Mixture. Atoms. . are the smallest unit of matter. . Matter. . is anything that has mass and takes up space. . A . ball is matter, water is matter, even the air you breathe is matter!. What is an atom. ? (cont.). 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. Section . 2: Ionic and Covalent Bonding. Objectives. Why do atoms form bonds?. How do ionic bonds form?. What do atoms joined by covalent bonds share?. What gives metals their distinctive properties?. The structure of atoms dictate their properties. How atoms combine dictate what we see in the many . minerals. in nature. . New technologies allow us to peer ever closer at the minute structures of minerals, down to the scale of individual atoms.. Bell work for November 25, 2018. Directions-Many Scientific words, such as . bond. , also have everyday meanings. Use context clues to write your own definition for each meaning of the word . bond. . Jennie L. Borders. Section 8.1 – Chemical Bonds, Lewis Symbols, and the Octet Rule. Whenever two atoms or ions are strongly attached to each other, we say there is a chemical bond between them.. There are three general types of chemical bonds: ionic, covalent, and metallic..
