molecular compound _________________________________________________
chemical formula ____________________________________________________
molecular formula ___________________________________________________
MAIN IDEAS AND SUPPORTING DETAILS
Write three supporting details for each main idea.
Main Idea
Supporting Details
Covalent bonds form
from shared electrons.
Bond lengths and energy
vary from molecule to
molecule.
APPLY MODELS
In the space below, draw two examples of an electron-dot notation, a Lewis
structure, and a structural formula. Try to show at least one example of multiple
bonds forming between two atoms.

6.3 Ionic Bonding and Ionic Compounds
TEKS 6E, 7B, 7C
KEY TERMS
Write your own definition for each key term.
ionic compound _____________________________________________________
formula unit ________________________________________________________
MAIN IDEAS AND SUPPORTING DETAILS
Write three supporting details for each main idea.
Main Idea
Supporting Details
Ionic bonds form from
attractions between
positive and negative
ions.
Differences in attraction
strength give ionic and
molecular compounds
different properties.
Multiple atoms can bond
covalently to form a
single ion.
