KOREY TREMBLAY CHEMISTRY Atomic Bonding
Review Protons and Electrons Nucleus Orbitals Atomic Radius
Goals Ability to answer questions about: 1. Electronegativity 2. Lewis Dot Diagrams 3. Different types of Bonding
Electronegativity Atomic radius Electronegativity number
Examples Sodium Chloride – NaCl Magnesium Bromide – MgBr 2
Examples Sodium Chloride – NaCl Magnesium Bromide – MgBr 2 Notice something about these examples?
Ionic compounds “Stealing” of electrons Metal and Nonmetal Electronegativity difference Octet rule
Lewis Diagrams – Ionic compounds Electrons belong only to one atom Each atom is charged Lewis diagram of Water Salt experiment
Covalent bonds Both atoms “share” the electrons Forms a stronger bond Octet rule Oxygen
Lewis Diagrams – Covalent bond Drawing a Lewis Diagram for O 2 Partial Charges (water) Hydrogen bonds
Hydrogen Bonding Based on attraction of charges No electrons are shared or transferred Penny drop experiment
Next week… VSEPR Like charges repel
Ionic Bonding. Elements Goal = Stability Elements want to be stable In order to be stable they need to fill their outermost energy level completely –
Chemistry Unit 4 Bonding Why do atoms bond? -to become more stable -a full valence shell of electrons -valence shell = outside shell How do atoms bond?
Chemistry Review. Jeopardy! 100 Atoms Where are the protons and neutrons found in an atom? The Nucleus.
Chemistry Notes Dot Diagrams Ionic Bonding Diagrams.
Chemical Bond The attraction between atoms that holds them together and makes them function as a unit.
In covalent bonding, the two electrons shared by the atoms are attracted to the nucleus of both atoms. Neither atom completely loses or gains electrons.
Types of Bonds. There are two main types of bonds that atoms can form Covalent Bonds Ionic Bonds.
IPC Notes Types of Bonds. Remember… Atoms combine by gaining, losing or sharing electrons in order to become chemically stable. Atoms become chemically.
BONDING. WHY ATOMS COMBINE -1 All atoms want a full outer shell Some atoms will lose electrons to empty their shells These become positively charged ions.
The Chemistry of Life Or Biochemistry Atoms, Molecules, Compounds, Chemical Bonds.
Ionic Bond bond formed by the giving or taking of electrons.
Chapter 3 – Atomic Structure. Elements Ionic Bonding Positively charged sodium is attracted to negatively charged chlorine to form sodium chloride (table.
6.1 Ionic Bonding HES Chemistry Unit: Ions and Ionic Bonds.
8.1 Covalent Bonds. Molecular compounds = 2 non metals that share 1 or more pairs of electrons… group is electrically neutral.
The Sharing and Transferring of Electrons
Ionic Bonding & Covalent Bonding. Ionic Bonding Ionic Bonding – TRANSFER of electrons Metals + Nonmetals = Ionic Bond.
Science 20 Unit A CHEMISTRY. Chapter 1: Aqueous Solutions 1.1 Structure of matter 1.2 Atomic bonding & properties 1.3 Breaking bonds 1.4 Concentration.
Unit 1 Chemical Bonding: Ionic 1.3 What are ions and how do they form? AIM: How do ions form and why? DO NOW: Draw the Planetary Model of the following.
ATOMS AND BONDING Chapter 5 Review game. Question Shows which elements and how many make up the compound NaCl, K 2 S, NaCaPSClAt Sodium=1 and Chlorine=1.
Chemical Bonding Chapter 6 General Chemistry Valence Electrons Valence electrons ______________________________ _______________________________________________.
Chemical Bonding. Chemical Bond The forces that hold groups of atoms together and make them function as a unit Bonding involves only the valence electrons.
Nature of Matter. Atom smallest unit of matter that cannot be broken down by chemical means.
Warm up Why are hydrogen bonds the weakest bond, ionic bonds stronger, and covalent bonds the strongest? What does it mean to be the strongest bond?
Topic 5: Bonding 5.4: Covalent Bonding AIM:. Do Now Draw the Lewis dot structure for magnesium Draw the Lewis dot structure for a magnesium ion Draw the.
Warm-up Describe what occurs before and during an ionic bond. If the bond is broken what happens to the atoms? Describe what occurs before and during a.
BASIC CHEMISTRY. An understanding of an atom’s structure is required to understand how chemical bonds form. The atom is the basic building block of all.
Chemistry Review Do you remember anything from science investigations?
Objectives I can compare the properties of ionic and covalent compounds with a Venn diagram. I can practice drawing Lewis Dot Diagrams of molecules by.
6.1 Ionic Bonding. Stable Electron Configurations When the highest occupied energy level of an atom is filled with electrons, the atom is stable and not.
Date: October 13, 2015 Aim #15: What role do electrons play in chemical bonding? HW: 1)Worksheet- Counting Valence Electrons (back) 2)Quiz (Inorganic Chemistry)-
Objectives Know atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.
Atomic Structure and Bonding Bonding. Specific Learning Outcomes Enter here.
Covalent Bonding What is a covalent bond?. Covalent Bonding What is a covalent bond? How is a covalent bond different from an ionic bond?
Chemical Bonding-Focus Ionic! Bonding: Ionic, Metallic, & Covalent.
Ionic Bonding. CA Standards Students know atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons.
10/6/14 Objective: How are ionic and covalent bonds formed? Do Now: Sodium’s atomic mass is 23 and atomic number is 11. How many protons are there? Neutrons?
CHEMISTRY PART 6 Ionic Compounds Charges of transition metals will be given in the periodic table as their formation is complicated.
Chemistry C2 Revision PowerPoint - Big ideas Ionic and Covalent bonding Metallic structures.
Bonding and Nomenclature Unit About 3 weeks Will discuss the bonds that elements form and how to name the compounds formed There are many rules and procedures.
Ionic Bonds and Compounds. The Octet Rule The Octet rule states that elements gain or lose electrons to attain an electron configuration of the nearest.
Ionic Compounds Compounds can be broken into several categories. The first type of compound we are going to study are ionic compounds. Ionic compounds.
Intro to Bonding: Part 2: Covalent Compounds (Type 3 Binary Compounds)
Complete the worksheet on the structure of the atom.
Ionic and Covalent Bonding 1. Bonding Atoms with unfilled valence shells are considered unstable. Atoms will try to fill their outer shells by bonding.
1. How do you know how many valence electrons an atom has? Day
Chemical Bonding The Formation of Compounds. Lewis Theory The attraction between electrons of one atom to the nucleus of another atom contribute to what.
Atom – the smallest unit of matter “indivisible” Helium atom.
