The Structure of the The atom is composed of a
negative, positive and neutral
Atom charge
Nucleus
The nucleus contains
protons which have a Electrons
positive charge. It also
They are very, very tiny so
contains neutrons which
the atom is mainly empty
have no charge
space. Electrons have a
negative charge
Na
Shells
The first shell always
contains two electrons when
full whereas the other shells
have a maximum of eight
electrons *Na being sodium with this
particular atomic structure.

Here's a taster:

Ionic bonding
It only occurs between a metal and a non-metal
It is formed from an attraction between positively charged
and negatively charged ions
Ionic bonding involves the complete transfer of electrons
from one atom to another
This means that elections will try to fill an empty shell of
an atom using the minimum amount of energy. So if there
is 7 in one outer shell and 1 in the other, the atom with 1
will lose its electron and the one with 7 will gain it
Remember that when an atom loses an electron it
becomes positively charged [e.g. 1+] whereas the atom
which gains an electron becomes negatively charged [e.
g. 1-]
