Covalent Bonds Nature
Electonegativity in a Covalent Bond
Phisical Properties of Covalent Bonds
Nomenclature
Isomers
100
How can you tell the difference between ionic and covalent compounds?
two nonmetals = covalent
metal and nonmetal = ionic
100
What is Electronegativity?
The ability of an atom to attract electrons toward itself
100
Compound with this type of bond are typically found as solids at room temperature.
Ionic Bonds
100
The formula for chlorine dioxide
ClO2
100
What is an isomer
Compounds with the same molecular formula but different structure (arrangements of the atoms)
200
Octet Rule
What is the rule that states atoms form compounds to achieve 8 valence electrons?
200
What are the two types of covalent bonds?
Polar Covalent Bonds Non-polar Covalent Bonds
200
Compound with this type of bond have very low melting points (sometime below room temperature).
Covalent Bonds
200
The name of O2
Oxygen gas or molecular oxygen
200
T/F All isomers of the same element will have the same types of covalent bonds
False
300
How do atoms obey the octet rule differently when forming ionic vs covalent compounds?
Ionic = steal electrons
Covalent = share electrons
300
If permanent marker gets on your clothes, what must you use to get it out?
A non-polar solvent
300
Compound with this type of bond are good at conducting electricity when dissolved.
Ionic bonds
300
The name of CH4
Carbon Tetrahydride
bonus point for methane
300
Identify how many of each element is in the diagram.

C = 6
400
Which type of bond is the strongest?
triple bond
400
What characteristic makes an ionic bond instead of a covalent bond?
A big difference in the electronegativity of the atoms.
400
Which type of compound is more likely to be soluble in ethanol?
Covalent
400
The name of Si2Br6
Disilicon Hexabromide
400
How many hydrogen are in the image.
24
500
What determines the bond length of a covalent bond?
Potential energy based on the attraction of the nuclei to the shared electrons
500
When is a a covalent bond formed instead not an ionic bond?
When the difference in electronegativity is below 1.7.
500
Compound with this type of bond are good at conducting heat and electricity in a solid form.
