Compounds
What are the two types of bonds
Ionic and Covalent Bonds
What are Ions
at atom or group of atoms having an electrical charge because of a loss or gain of electrons
What makes up an Ionic Compound
non metal and a metal
Draw NH3 as a Lewis Structure
Write on board!!!
What molecular shape is H2O
Bent
Example of a Ionic and Covalent compound
Ionic - Na+ Cl-
Covalent -H2O
Ions with a positive charge
Cations
What happens to electrons in covalent bonds
Electrons are shared
Draw CO2 as a Lewis Structure
Draw on the board!!!
What molecular shape is NH3
Trigonal Pryramid
Elements in groups 1A to 7A reach what with other elements by forming ionic or covalent bonds to produce a stable electron configuration
Octet Rule
Ions with a negative charge
Anion
What charges do Covalent Bonds have
They have none
Draw CH4 as a Lewis Structure
Draw on the board!!!
What is the angle in a Linear shape
180 degrees
Does not apply with transitions metals
Octet Rule
What ionization energy do metals have
Low Ionization Energy
What state of matter are ionic bonds found in
Solid at Room Temp
How many valence electrons are available in CO2
16 valence electrons
What is the angle in a Bent shape
120 or 104 degrees
What is happening to the electrons in Sodium Chloride
Sodium atoms lose electrons and Chlorine gains electrons
What nonmetal groups have high ionization level
group 15, 16, 17, and 18
How strong is the attraction between molecules in Covalent Bonds
Very Weak Attraction
How many valence electrons are available in CH3I
14 valence electrons
Example of a Tetrahedral?
It varies - you must have 4 bonds off center. Example CH4
