Covalent Bonds
Difference between electrons in Covalent and Ionic bonds.
In covalent bonds, electrons are shared while in ionic they are transferred.
Physical Attributes of ionic bonds.
High conductivity, boiling point, solubility, etc.
What effect on water does hydrogen bonds have that makes the surface more tense?
Surface tension.
WHAT DOES MALLEABLE MEAN ?!!!?!?!?!?!?!!?
Common example of a covalent bond (hint: you drink it everyday).
Water.
Common example of an ionic bond (hint: it is commonly used in foods and saltine crackers)
NaCl (salt)
Common example of a hydrogen bond.
Water.
Why is water polar?
Because there is a large difference in electronegativity between the 2 different elements.
Why are Metallic Bonds malleable?????????????????????????????????????????????????
Sea of electrons makes it easily flexible.
Physical Attributes of Covalent Bonds
What is ionic bonds formed between?
Metals and nonmetals.
Effect of heat on surface tension.
High temp.= Weak surface tension.
What is a dipole?
A molecule with 2 poles.
Difference between Metallic Bonds and Ionic ones.
Metallic Bonds are malleable.
What are the two types of Covalent Bonds?
Polar and Non-polar.
Ionic.
Effect of Cold on surface tension.........
Low temp.= Strong surface tension.
BONUS: What is H-H?
Hydrogen.
Metallic ones are malleable.
What makes up a nonpolar covalent bond?
Two of the same atom.
What is a polyatomic ion?
An ion formed from 2 or more covalently bonded elements.
What type of force is Hydrogen Bonding.
Intermolecular Force.
BONUS: WHY DOES ICE FLOAT IN WATER??
low density
