Picture this!
Draw 2 lines (one labeled ionic and the other covalent)
This style of line connects the atoms in an ionic bond drawing.
This style of line connects the atoms in a covalent bond drawing.
What is . . .
Ionic = arrow
Covalent = regular (connecting) line
In this type of bond, electrons are shared.
What is . . .
a covalent bond?
In this type of bond, electrons are given/taken.
What is . . .
an ionic bond?
The small numbers to the lower right of an element symbol such as the 2 in H2O are called this.
What is . . .
a subscript?
This type of animal is in a glass case in the lobby of North High.
What is . . .
a polar bear?
This is a Lewis structure model for
K2O
What is . . .
check each other for two K atoms with one dot giving (arrow) to one O atom with 6 dots
This is the name for:
SO2
What is . . .
sulfur dioxide?
This is the name for BeF2
What is . . .
beryllium fluoride?
In the molecule NH3, there are this many N atoms and this many H atoms.
What is . . .

3 H atoms
Herbert Hoover is the only U. S. president from this state.
What is . . .
Iowa?
This is the Lewis structure drawing for CBr4
What is . . .
Check each other for a central C atom with 4 dots connected to 4 Br atoms that each have 7 dots
Of the following, this would be a covalent molecule:
NaCl
PbSO4
CF4
AlCl3
What is . . .
CF4?
(Because it has only non-metals)
This is the name of CuCl2
What is . . .
copper (II) chloride?
Must have the (II) for credit.
tetraphosphorous pentasulfide
What is . . .
P4S5 ?
The official motto of Des Moines East High is
"For the service of __________________."
What is . . .
humanity?
This is the Lewis structure model for an NO2-1 ion.
What is . . .
Check each other for an N atom with 5 dots connected with lines to two O atoms that each have 6 dots.
The N atom will share 2 bonds with one O atom and 1 bond with the other O atom. This leaves one O atom with an opening. The group can still gain one more electron which makes this a polyatomic ion.
This is the name of:
N2O4
What is . . .
dinitrogen tetroxide?
This is the name of KNO3
What is . . .
potassium nitrate?
This is the formula for iron (III) oxide.
What is . . .

Challenge: This is the Lewis structure for
Ca(OH)2
Check each other . . .
- Drawing includes arrows from one Ca atom with 2 dots toward two OH ions
- Within each of the two OH ions, there is one O atom with 6 dots bonded with a line to an H atom with 1 dot
This is the name of
As4O10
What is . . .
tetrarsenic decaoxide ?
This is the name of
Pb(SO4)2
What is . . .
