CH 7 READING GUIDE – Ionic and Metallic Bonding! 7.1: Ions (p. 194-199) 1) What are . VALENCE ELECTRONS? 2) Fill in the chart below for each element: Element # valence e- electron dot structure (Lewis Structure) Rb S Sr Al C Kr P I 3) How many valence electrons do atoms of the noble gases have?
Every ionic compound having some percentage of covalent character according to Fajan's rule. But from the octet rule HF should have been a purely covalent compound but actually it has some amount of ionic character in it, which is due to the electronegativity difference of H and F. Similarly knowing...

1. In an element, only one type of atom is pres- ent. In a compound, atoms or ions from two or more different elements are chemically combined. 2. (a) Ionic and covalent (b) In ionic compounds, one or more electrons transfers between atoms, producing posi- tive and negative ions. These ions are attracted together because of their opposite charges.
Likewise, the Na and Cl atoms in NaCl have an electronegativity difference of 2.1, and the Mn and I atoms in MnI 2 have a difference of 1.0, yet both of these substances form ionic compounds. The best guide to the covalent or ionic character of a bond is to consider the types of atoms involved and their relative positions in the periodic table.
(Spectator ions are ions that remain the same in their original states before and after a chemical reaction.) Example: Write a complete, total ionic and net ionic equations for the reaction of aqueous sodium carbonate with aqueous barium nitrate.

ionic compounds are neutral. A repeating pattern of positive and negative ions in a compound is called an ionic lattice. How do covalent compounds form? Sometimes atoms share electrons instead of losing and gaining them. If atoms share electrons, they form covalent compounds. Covalent compounds form when non-metal atoms bond 1.
