Ionic
What type of elements form an ionic bond?
What is a metal and a nonmetal?
What type of elements form a covalent compound?
What is the following name of this polyatomic ion?
Where would you find this name in the reference table?
-SO4 -2
What is sulfate?
What is table E?
Draw the lewis structure of oxygen.
check with teacher
The two categories of bonds are called what?
What is ionic and covalent/molecular bonding?
The valence electron of the metal gets transferred to the nonmetal.
In terms of metals or non metals, describe how electrons are transferred or shared within an covalent bond.
The electrons are shared between both of the nonmetals.
- PbO2
What is lead (II) oxide?
Draw the lewis structure of KCl *show electron transfer*
check with teacher
Which form of matter has particles that are arranged in a crystalline structure?
What is a solid?
What are three properties of ionic compounds?
What is high melting point, high boiling point, forming of crystals, soluble in water, conduct electricity in solutions and as liquids.
What are three properties of covalent compounds?
What is low melting point, low boiling point, do not conduct electricity?
Write the name of the following covalent compound.
CF4
Draw the lewis structure for the following compound.
NH3
Check with teacher.
What are the number of electrons within:
-single bond
-double bond
-triple bond
- 2 electrons
-4 electrons
-6 electrons
Explain how and why you need to specify the charge when writing an ionic bond with a transition metal.
Transition metals possess more than one charge/oxidation state. A roman numeral in ( ) will show the charge of that specific ion for the compound being asked.
Which of the following chemical bonds is MOST polar?
1. Te-H in H2TE
2. Se-H bond in H2Se
3. S-H bond in H2S
4. O-H bond in H2O
What is the O-H bond in H2O
EN= 1.2
Sr(C2H3O2)2
Explain whether or not it is polar or nonpolar.
- CCl4
Check with teacher.
Nonpolar and due to its symmetry.
What is network solids and covalent bonding?
Explain how combining Al and Br require 3 Br.
Al has a charge of 3+. Br only has a charge of -1. Therefore, to have the net charge equal to 0, you need 3 Br to get the anion charge to 3-.
Which of the following substances are considered covalent? EXPLAIN WHY.
1. C6H12O6 (s) and KI (s)
2. KI (s) and NaCl (s)
3. C6H12O6 (s) and HCl (g)
4. NaCl (s) and HCl (g)
Choice 3 because each compound just contains nonmetals. All the other choices are ionic.
Write the chemical formula for the following compounds:
1. potassium permanganate
2. hexaboron monosilicide
What is:
1. KMnO4
2. B6Si
Draw the following Lewis Structure: Na + O
Check with teacher.
In terms of electronegativity, why a P-Cl bond in a molecule of PCl5 is more polar than a P-S bond in a molecule of P2S5.
The P-Cl bond is more polar than the P-S bond because the electronegativity difference between P and Cl is 1.0, whereas it is only 0.6 between P and S.
The greater the electronegativity difference, the more polar the bond.
