Learning Objectives. Express the arrangement of electrons in atoms . using Lewis . valence electron dot structures. Electron Arrangements. Valence electron. – an electron in an atom’s highest occupied energy level. Purpose:. The purpose of Lewis Dot Diagrams is to display an elements valence electrons in a short hand way. These valance electrons determine what chemical families and groups (vertical columns) different elements fall into. The arrangement of these valance electrons tell us about the properties of elements, as well as how element behave in chemical reactions. . Review. Electrons are the negatively charged part of the atom. Electrons are found in . orbitals. around the nucleus. We write the electron configuration of the element to see the different . orbitals. How they are formed. Valence Electrons. Valence Electrons of an atom are the electrons that are in the outermost s and p sub shells. (ONLY S AND P). To determine how many electrons are in your valence shell, look at where your element is on the periodic table.. Valence Electrons. Chemistry - Shearer - Standard 1. 1. Students . know how to use the periodic table to determine the number of electrons available for bonding. . Why are Valence Electrons Important?. What is a valence electron?. The electrons in the last shell or energy level. These determine how an atom behaves, reactivity, bonding. These are the only electrons we need to worry about from now on. Valence Electron Interaction and Charges. The Role of Electrons in Bonding. The sharing or transfer of . electrons . is what holds atoms together . in a . compound. Typically, only the electrons in the . What is a Valence Electron?. Valence electrons. are the electrons in the outer shell . that bond with other atoms. What is a Valence Electron?. Valence electrons. are the electrons in the outer shell . How does the interaction of valance electrons form chemical compounds?. Bohr Model. What is a Bohr Model?. Shows all the protons, neutrons, and electrons contained within an atom.. Protons and neutrons are drawn in the Nucleus.. Do not. . start drawing on the whiteboards. Have . your periodic table out. Any questions from your review guide?. How many valence electrons does sodium have?. How do you know?. How many valence electrons does chlorine have?. 4.2. Main Group Elements A. The main group elements are group A elements: 1-8, and they do not include the transition metals or the rare earth elements (lanthanides and the actinides).. Following the Octet Rule. Atomic number = Total number of electrons. The group number tells you the amount of valence electrons an element has.. The metals are on the left side of the periodic table. The nonmetals are on the right side of the periodic table. .
