- Fundamental Ideas
- An element is a substance consisting of
atoms which all have the same number
of protons - i.e. the same atomic
number.
- The sub-atomic structure of a carbon atom
- A table to show relative charges
- A chemical bond is a mutual
attraction between two atoms
resulting from a redistribution of
their outer electrons.
- An element is an
atom or molecule
made of a single type
of atom. A compound
is a molecule made of
two or more different
elements.
- Atoms
- The
overall
charge of
an atom is
0
- The number of
protons in the
nucleus is equal to
the number of
electrons
- All atoms of an element
have the same number
of protons.
- Atoms of different
elements have different
numbers of protons
- Atoms are arranged in
the modern periodic
table in order of their
atomic number (proton
number)
- The
overall
charge of
an atom is
0
- Chemical bonding
involves either
transferring or sharing
electrons in the highest
occupied energy levels
of atoms.
- Elements in group 1 of the periodic table
all have similar chemical properties.
They all react with non-metal elements to
form ionic compounds in which the metal
has a single negative charge.
- Elements in group 7 of the periodic table,
the halogens have similar chemical
properties. They react with alkali metals to
form ionic compounds in which the halide
ions hhave a single negative charge.
- An element is a substance consisting of
atoms which all have the same number
of protons - i.e. the same atomic
number.
