Chemical bonding Flashcards
1
Q
What types of bonds are there?
A
- metallic bonding
- covalent bonding
- ionic bonding
2
Q
What is the definition of a metallic bond?
A
- metallic bond is the elctrostatic forces of attraction between the lattice of positive metal ions and “sea of mobile electrons”
3
Q
What do ionic compounds form?
A
- giant ionic compounds
4
Q
What is the giant ionic compound made up of?
A
- oppositely charged ions
- held together by strong ionic bonds
5
Q
What are the physical properties of ionic compounds?
A
- high melting and boiling point
- exist as solids at room temperature
6
Q
Why do most ionic compounds have high melting and boiling points?
A
- electrostatic forces of attraction between oppositely charged ions are very strong
- large amount of energy absorbed to overcome these strong electrostatic forces of sttraction
7
Q
What is the factor affecting ionic bond?
A
- charge of cations and anions
