Deconstruction - What is the best method to classify a chemical substance?
Type of bonding
Ionic Bonding
Occurs during the transfer of electrons
Binding energy is higher than the metallic bond
Low conductivity
Non-directional bond
Present only in one state: solid-state
Non-malleable
Higher melting point

Covlent Bonding
Occurs when 2 atoms share their valence electrons
Binding energy is higher than the metallic bond
Very low conductivity
Very low conductivity
Present only in all 3 states: solid, liquid, gases
Non-malleable
Lower melting point
1 more item...
Metallic Bonding
The attraction of metal cations/atoms and delocalized electrons
Binding energy is less than covalent and ionic bond
Has high electrical conductivity
Non-directional bond
Present only in one state: solid-state
Malleable
High melting point

Risk assesments
unsafe equipment used
Bunsen bruner
glass beacker
irresponsible useage of equiment
the substnacing being harmful
Limiations
of equipment and the resources given
resitution in amount of testing needing to be done
the duration given to test as the perfect amount can't be classified yet
WHta is chemical
relating to chemistry, or the interactions of substances as studied in chemistry. the real physical matter of which a person or thing consists and which has a tangible, solid presence.
Ways to classify the chemcil subdtance
Solublity in solution test
Melting point/ boiling point
conductivity of solid
malleability
