Unit 1- Bonding Flashcards
The definition of Metallic Bonding
The electrostatic force of attraction between fixed positive cores of atoms and the shared delocalised electrons.
Do metals conduct electricty
Metals conduct electricity in all states
Melting points of metallic bonding
medium
Is Metallic bonding solid at room temperature
Yes
Are metallic bonding soluble in water
No
Diatomic elements
iodine, bromine, chlorine, fluorine,Oxygen, nitrogen and hydrogen.
Definition of covalent molecular
The electrostatic force of attraction between a positive nuclei and a shared pair of electrons
melting points of covalent molecular
low melting points as they only have to bread weak bonds
Is ionic bonding soluble in water
Yes
Do covalent molecular conduct electricity
No, as they have no charged particles that are free to move
Definition of covalent network
the electrostatic force of attraction between a positive nuclei and a shared pair of electrons
Melting point of covalent network
very high, as they have to break strong bonds which require a lot of energy
Does covalent network conduct electricity
no, except graphite
Definition of ionic bonding
the electrostatic force of attraction between oppositely charged ions
Does ionic bonding conduct electricity as a solid
No, because the ions are not free to move
