IONIC, COVALENT, AND METALLIC BONDING DAY 2 – IONIC BONDING 1

WARM UP CHECK MY WORK. WHICH ONES ARE RIGHT, WHICH ONES ARE WRONG? FIX THE ONES THAT ARE WRONG! Li He MgSi TIME: 4 MINUTES WHEN DONE: Take out “Ion Practice” and/or Show me UPDATED “Ionic Bonding Tutorial”

AGENDA ION PRACTICE REVIEW CHEMICAL FORMULAS ACTIVITY: IONIC BONDING AND COMPOUNDS LEARNING TARGET CHECK IN NEXT CLASS - DEMO: ELEPHANT TOOTHPASTE

LEARNING TARGETS I CAN DESCRIBE HOW IONIC, COVALENT AND METALLIC BONDS ARE FORMED BETWEEN ATOMS

IONIC BONDING PRACTICE TAKE OUT: Ion Practice SHOW: Me completed assignment for full credit YOU WILL: Share your answers with class under the document camera TIME: 3 minutes WHEN DONE: Be ready to write answer under the document camera

CHEMICAL FORMULAS OPEN TO: NEXT AVAILABLE RIGHT-HAND PAGE SET UP: CORNELL NOTE TITLE: CHEMICAL FORMULAS ESSENTIAL QUESTIONS: WHAT IS A CHEMICAL FORMULA? TIME: 2 MINUTES WHEN DONE: FIND MAGNESIUM AND CHLORINE ON THE PERIODIC TABLE

ENDOCRINE DISRUPTORS EQ: HOW DO ENDOCRINE DISRUPTORS IMPACT HUMANS? Chemical Formulas EQ: What is a chemical formula? 3/30 Substances that are held together by ionic bonds are called ionic compounds. A chemical formula for an ionic compound shows the ratio of positive to negative ions in the compound. NaClMgCl 2 For every 1 positive Na ion, there is 1 negative Cl For every 1 positive Mg ion, there are 2 negative Cl ions Al 2 O 3 For every 2 positive Al ions, there are 3 negative O ions

IONIC BONDING ACTIVITY DRAW: The Lewis Dot Structure for each atom USE: The manipulatives to show the transfer of electrons DESCRIBE: What you did WRITE: The ion WRITE: The ionic compound formula (remember to use ratios) TIME: 28 MINUTES WHEN DONE: Turn into class box and open to your learning target page

LEARNING TARGET CHECK IN TURN TO: The Learning Target Page for Unit 7 FIND: Two different colored highlighters First color: Highlight supporting Targets 1.1, 1.2 and 1.3 In the Page # Column, write the page number(s) for your “Intro to Bonding” notes Second Color: Highlight supporting Targets 2.1, 2.2 and 2.3 In the Page # Column, write the page number(s) where your wrote your answers for the “Ionic Bonding Tutorial” TIME: 4 MINUTES WHEN DONE: SHOW ME
