Name __________________________ Date _______________ Title in Textbook _____________________________ Page Numbers _________ Reduce & then Recite Record for Review What is an atomic number? The number of protons and electrons in a neutral atom is equal - Create questions which elicit critical thinking, not 1 word answers - Write questions directly across from the answers in your notes - Leave a space or draw a pencil line separating questions Bohr diagram What is a Bhor Diagram compound covalent bonding ionic bonding What ions is a compound Lewis diagram molecule valence What iselectrons Covalent Bonding - Write headings and key words in colored pencil Take sufficient notes with selective (not too many words) & accurate paraphrasing Skip a line between ideas and topics Use bulleted lists and abbreviations Correctly sequence information Include diagrams or tables if needed for clarification or length A bhor diagram is a diagram that shows how many electrons are in each shell surrounding the nucleus. A compound is a pure substance that is composed of two or more atoms combined in a specific way. In covalent bonding atoms slightly overlap and one unpaired electron from each atom will pair together. Both atoms are attracted to the same pair of electrons forming covalent bonds What is Ionic Bonding? Ionic bonding is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds What are Ions? An ion is a atom that gains or loses electrons What is a Lewis Diagram? A lewis Diagram is a diagram that illustrates chemical bonding by showing only an atoms valance electrons and the chemical symbol. What is a molecule? A molecule is a group of atoms in which the atoms are bound together by sharing one or more pairs of electrons. What are Valance electrons The electrons in the valance shell. What is a Atom An atom is the smallest part of the element that retains the properties of the element. Name __________________________ Date _______________ Period _____ Page ______ What is a Chemical Change What are subatomic Paritcals? What is a proton What is a Neutron What is a Electron What is a Period What multivalent What is a Stable Octet Chemical changes are changes in the way the atoms and molecules in a pure substance are arranged and interconnected. Subatomic particals are the particals that make up an atom A proton is a subatomic partical in an atoms nucleus with a +1 charge A neutron is a subatomic particle in an atoms nucleus with a neutral electric charge A electron is a subatomic particle in an atoms nucleus with a -1 charge. Each row on the periodic table from (Top to Bottom) Multivalent means they can form ions in more than one way, depending on what chemical reaction they undergo. A octet refers to a complete set of eight valence electrons.

What is a anion Atoms of non-metals may gain electrons from other atoms, forming anions. What is a Covalent A covalent compound is formed when non-metallic atoms Compound? share electrons. What is a Diatomic molecule A diatomic molecule is a pair of atoms that are joined by covalent bonds What is a Transition metal? Transition metals include familiar elements such as iron, nickel, copper, silver and gold Reflect & Recapitulate In your own words and in complete sentences, write a 3 – 4 sentence summary paragraph. Your summary should cover the main concepts of the notes, be accurate, and have adequate details. In this unit we learned how to properly navigate the periodic table by using family such as groups Groups, families and rows. We learned two ways to show what an atom would look like using bhor Using Bhor and Lewis diagrams. We learned what parts atoms have such as Electrons, protons Protons, Neutrons, Etc… and what happens when atoms borrow or lose electrons and what they become They become and what they are called.
