Properties of
Substances
- Ions
- A charged particle. A neutral
atom that loses electrons
becomes a positive ion but
atom that gains electron
becomes a negative ion
- Type of particles:-
consists negative
ions and positive
ions
- Condition at room
temperature:- solid
- Boiling and
melting point:-
high
- Arrangement of
particles:- very
close
- Forces of
attraction:- Strong,
through ionic
bonding
- Electrical conductivity:-
Cannot conduct electric in
molten state but can conduct
electric in aqueous or molten
states
- Atoms
- The smallest, indivisible
particle of an element
that can take part in a
chemical reaction
- Type of particles:-
consist of atoms
- Condition at room
temperature:- solid
except mercury
- Boiling and melting
point:- high
- Arrangement of
particles:- very close
- Forces of attraction
between particles:- very
strong through metallis
bonding
- Electrical conductivity:-
conducts electricity in
solid and molten states
- Molecules
- Consists of two or more
atoms of the same type
or of different types that
chemically combined
together
- Type of particles:-
consists of
molecules
