Question 3!
Let’s try this again!!

Ionic Bond
A chemical bond that uses a metal ion and a nonmetal ion, or sometimes a polyatomic, but must use two oppositely charged ions. The metal gives more electrons and forms a cation. The electrons go to the nonmetal and form an anion. A cation is positively charged and an anion is negatively charged. When these two come together they form an ionic bond.
Characteristics:
Dissolve quickly in water
Conduct electricity
High melting temperatures
Solids
Example:
NaCl

Covalent Bond
A chemical bond that shares valence electrons between atoms. These atoms do not have to be of the same element. The strength of the bond depends on the polyatomics.
Characteristics:
Low melting and boiling points
Solids, liquids gases
Do not dissolve in water
Do not conduct electricity
Example:
CO2

Polar Covalent Bond
A chemical bond that sharing electrons is unequal. The charges of some atoms are separated with some atoms being more charged than the other. The atom attracting electrons with another atom present is property called electronegativity.
Characteristics:
Share electrons unequally
Electronegativity has to be greater than .4
Strong forces
Partially negative and partially positive
Example:
H2O
