• ATOM= An atom is the base for all other particles and makes up everything
...
• MOLECULE= A molecule is anything with a bond
...
For
example: 02 is two oxygen's bonded together
...
E
...
) Fe, N2, Ag
•
COMPOUND= A compound is two or more types of atoms that have been
chemically bonded
...
INSIDE AN ATOM:
• Nucleus
• Proton
• Neutron
• Electron
Periodic Table
7 is the mass number (which is always
bigger)
7
Li
3 is the atomic number, (number of
protons in the element)

• The periodic table is a table that shows elements
...
• The elements are ordered by their atomic number, to make it
clearer for us to see elements with a similar atomic structure
...
The sections of the periodic table:
o Ionic Bonding= When
electrons are transferred
from one atom to another
...
Because positive
and negative charges attract
it makes an ionic bond
...
oWhen non-metals bond with
non-metals they share
electrons and form
COVALENT BONDS
...
We use the formulas and symbols of all the substances in the
reaction to work out the products
...
II
...
Under the reactants side of the equation, count how many of each
atom we have
...
Under the products side of the equation, count how many of each
atom we have
...
Balance both sides using big numbers in front of the compounds and
elements/atoms to make them the same amount
...
Reactivity series links metals in order
of how reactive they are
...
Metals that are less reactive
than carbon CAN BE
EXTRACTED from their ores
by reduction
The way we extract a metal
from its ore depends on its
place in the reactivity
series
...
For the elements more
reactive than carbon a more
detailed process is used to
get the ores
...
For the metals between
carbon and hydrogen we
react the elements with
carbon/carbon monoxide
