PPT-Ionic and Covalent Bonds

Ionic bonds result when electrons are transferred between atoms Covalent bonds result when valence electrons are shared between atoms Types of Bonds Formed between a metal and a nonmetal. Unit 1 – Chemical Changes and Structure. Bonding and Structure. The Formation of Bonds. Bonds. are . electrostatic forces. (attractions between positive and negative charges) which hold atoms together.. Molecular Geometry. Ch. 6 Sections 1-4 Review. In general, what determines whether atoms will form chemical bonds?. Atoms will form a chemical bond if their potential energy is lowered in doing so.. Describe the difference between ionic and covalent bonding.. VSEPR Theory, Polarity, and using . Electronegativity. Covalent . Bonds. Forms when 2 atoms share a pair of valence e. -. A. Types of Covalent Bonds. 1. . Single Covalent Bond . – two atoms share . Co = Together. The Octet Rule. The octet rule says that all atoms want to have eight valence electrons, like the noble gases.. One way that atoms can follow the octet rule is by giving and taking electrons… ionic bonding. Including Naming. Note: We likely won’t make it to covalent nomenclature, this is the one students find FAR easier than ionic. Please refer to the videos and naming hand out for help with this, and as always office hours, discussions, and . COVALENT BOND. bond. formed by the . sharing . of . electrons . Covalent . Bonds. Between nonmetallic elements of similar electronegativity. .. Electronegativity = how badly an atom wants to add an electron (non metals have higher electronegativity). Bonding Discussion. Bonding. . Ionic. . Covalent. . Metallic. Determined by difference in Electronegativity between atoms.. Ionic . Compounds. Crystalline . solids (made of ions) . High melting and boiling points . cation. bonds with Bromine.. Write the formula for . . gold(I) sulfide.. In the ionic compound Co. 3. N. 2. ,. which . cation. is present? . . Co (II) or Co (III). Ionic Bonds Containing . Transition Metals. Text:. Ch 8 (all except sections 4,5 & 8). Ch 9.1 & 9.5. Ch 10.1-10.7. My Name is Bond. Chemical Bond. PART 1: . Ionic & Covalent Bonding. Chemical Bonds. A chemical bond is an attraction between 2 atoms or ions.. Covalent Bonds. Covalent bonds:. occur between two or more . nonmetals. ; electrons are . shared. not transferred (as in ionic bonds). The result of sharing electrons is that atoms attain a more stable electron configuration.. Covalent bonds . result from the . sharing . of electrons. between two atoms.. A covalent bond is a . two-electron bond . in which the bonding atoms share valence electrons.. A . molecule . is a discrete group of atoms held together by covalent bonds.. Chapter 17- How Atoms Bond and Molecules Attract The Big Idea: Atoms and molecules are sticky 17.1 Electron-Dot Structures Valence electrons= electrons in outermost shell Electron- dot structures: a series of dots surrounding an atomic symbol Section 9.1 – Bonding of Atoms. Ionic and Covalent Bonds. Ionic. : Conduct electricity, high MP, high BP, dissolve in water.  . Covalent. : Do not conduct electricity, low MP, low BP, do not dissolve in water. Bioc. . 201. بسم الله الرحمن الرحيم. 1. What is Biochemistry?. Simplest definition: . “Chemistry of the living cell”. Uses basic laws of . chemistry. and . biology. to explain processes of living cells..
