Chemical Bonding Learning TargetsPower StandardDescribe, explain and predict the multiple ways in which chemical bonding occurs.Knowledge Targets“What I need toknow!”I can define the terms chemical bond and chemical bonding.Reasoning Targets“What I can do withwhat I know.”I understand which elements on the periodic table will bond and which ones won’t and why.I can use the group / family number of an element to determine its oxidation number and Ican use the oxidation number to determine what an element would do with its valenceelectrons in order to achieve a full outer energy level.I can discuss the process of metallic bonding, and I can relate the properties of metals to thelattice arrangement created.Skill Targets“What I candemonstrate.”Product Targets“What I can make toshow my learning.”I can compare the oxidation numbers of two elements to determine their bondingcompatibility.I can list similarities and differences between ionic, covalent, and metallic bonding.I can explain the process of ionic bonding verbally and diagrammatically.I can explain the process of covalent bonding verbally and diagrammatically.

Introduction to Chemical Bonding: Episode 501Objectives:

Physical ScienceIntroduction to Chemical try/501A chemical bond - forms when 2 or more atoms rearrangeto increaseionic bond - forms when valencefrom one atom to anothercation – atomareelectrons to becomecharged anion - atomelectrons to become.chargedIn ionic compounds the ions are arranged in aforces hold the ions together.Properties of ionic compounds: highandpoints - not easily electricity whenorbecause the ions are free tocovalent bond -Covalent compounds havetogether.are., formingforces holding theProperties of covalent compounds: lowerandpoints Many covalent compounds areliquids or gases. – easier to are notof electricity

electronegativity - property that tells how strong an atom’sis for.Since oxygen has aelectronegativity than hydrogen,oxygen holds onto shared electrons, giving the oxygen acharge and the hydrogen a partial charge.metallic bond –electrons areproperties of metals:1.2.3.4.(creates a “ ofnegative”)
