CHAPTER 3 CHEMICAL BONDS

CHAPTER 3 CHEMICAL BONDS. The world around us is composed almost entirely of compounds and mixture of compounds. Most of the pure elements also contain many atoms bound together, for example, diamond is a native form of carbon, in which a large number of carbon atoms are bound.

Ionic and Covalent Bonding

Ionic and Covalent Bonding. Chapter 9. Lewis Electron-Dot Symbols. A Lewis electron-dot symbol is a symbol in which the electrons in the valence shell of an atom or ion are represented by dots placed around the letter symbol of the element.

Covalent Compounds

Covalent Compounds. Why do atoms bond?. When a + nucleus attracts electrons of another atom Or oppositely charged ions attract( ionic bonds-metals and nonmetals) We know the octet rule- atoms tend to gain or lose or share e - in order to acquire a full set of 8 valence e -. Properties.
