    Atomic Structure

    The atom is made up of three sub-particles – the proton (+ve. and neutron (no charge. that are located in the nucleus of the atom and the electron (-ve charge. that is found orbiting the nucleus.

    The nucleus has a positive charge.

    The electrons are arranged in energy levels around the nucleus. Two electrons occupy the first, eight the second, eighteen the third.

    Within the energy levels are sub-shells .

    The region the electrons are said to occupy is called an orbital.

    The four types of orbital are:

    s-orbitals – spherical can hold 2 electrons.

    p-orbitals – dumb-bell shaped, they go around in three’s (px, py, pz. – so hold altogether a maximum of six electrons.

    d-orbitals are complicated in shape – they are grouped in five’s hence can hold a maximum of 10 electrons.

    f-orbitals are complicated in shape – they are grouped in seven’s – so altogether can hold 14 electrons.

    The order that electrons fill is as follows:

    1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d,
