C1- Atomic structure and the Periodic Table
Atoms
they contain
Protons, Neutrons and Electrons
Protons
found in the
nucleus
have a
relative mass of 1
has a
charge of +1
The
number of protons and the number of electrons is equal
in an atom.
the charges
cancel out
Neutrons
have a
relative mass of 1
does not have a charge
Electrons
moves around the atom nucleus
they have a
relative mass
that is taken as
0
(but
"very small"
is viable)
has a
charge of -1
atoms are neutral (no overall charge)
this is because -
and neutrons don't have a charge
Ions
are exceptions as the
number of protons and electrons are not equal
Nuclear symbol
An atom's
nuclear symbol
states the
Atomic (Proton) Number and the Mass Number
The
atomic (proton) number
tells you the
number of protons and electrons
the element has.
to figure out the
number of neutrons
in an atom all you have to do is
subtract the atomic number by the mass number.
the
mass number
tells you the
total number of protons and neutrons in an atom.
Elements
consistent of-
the
number of protons determines which element the atom is.
elements are consistent of
atoms with the same atomic number
there are
about 100 elements
all atoms of a certain element has the same number of protons
representations
each element is
represented by a symbol
.
e.g.
Oxygen = O
Sodium = Na
some representations make sense, meanwhile others don't
Isotopes
isotopes are the same element with a
different number of neutrons
the atomic number is not affected
e.g.
carbon-12 = 6P, 6E, 6N
carbon-13 = 6P, 6E, 7N
compounds
atoms join to make compounds
this is when
two or more different elements are chemically combined
to make bond
electrons must be taken away, given or shared
electrons are the only thing involved during involved during reactions.
there are two types of bonding.
ionic
ionic bonding involves the
giving away or taking of electrons.
the products of the reaction will have a
positive or negative charge
a
metal
ion will have a
positive charge.
a
non-metal
ion will have a
negative charge.
they tend to
between a metal and non-metal
covalent
covalent bonding involves the
sharing of electrons
they tend to be
between two different non-metals
