Nuclear Fission

Nuclear Fusion

Radioactive Isotopes

Looking at Alpha, Beta and Gamma Radiation

NUCLEAR FUSION

NUCLEAR FUSION is the jointing of two small nucleus to form a larger nucleus

NUCLEAR FISSION

NUCLEAR FISSION is the splitting up of a large nucleus into two smaller nuclei of roughly the same size

HALF LIFE

The HALF LIFE of a radioactive element for its activity to decrease by half

RADIATION

ALPHA RADIATION is fast moving helium muclei ejected from the nuclei of radioactive atoms

BETA RADIATION is high-speed electrons ejected from the nuclei of radioactive of radioactive atoms

GAMMA RADIATION is high-frequency electromagnetic radiation emitted from the nucleus of a radioactive atom

Types of Radioactive Decay + Penetrating power

RADIOACTIVITY

RADIOACTIVITY is the disintegration of decay of the nuclei of certain atoms with the emission of one or more types of radiation

ISOTOPES

Atoms of an element that have the same number of protons but different numbers of neutrons are called ISOTOPES of that element

MASS NUMBER

The total number of protons and neutrons int nucleus of an atom is called the MASS NUMBER (A) of that atom

ATOMIC NUMBER

The ATOMIC NUMBER (Z) of an element is the number of protons in the nucleus of an atom of that element

ENERGY LEVEL

An ENERGY LEVEL is a fixed energy value that an electron can have in an atom

EMISSION SPECTRUM

when light from a luminous source undergoes dispersion the resulting pattern is called a EMISSION SPECTRUN

X-RAYS

X-RAYS are high frequency electronmagnetic radiation produced when high speed electrons in a cathode ray tube strike a metal target that has a high melting point

PHOTON

The PHOTON is a packet of electromagnetic energy. The energy (E) of a photon is given by E=hf where f is its frequency and h is Planck's constant

THE PHOTOELECTRIC EFFECT

The PHOTOELECTRIC EFFECT is the emission of electrons from the surface of a metal by electromagnetic radiation of a suitable frequency

THE PHOTOCURRENT IS DIRECTLY PROPORTIONAL TO THE INTENSITY OF LIGHT

The Photoelectric Effect

ELECTRONVOLT (ev)

The ELECTRONVOLT (eV) is the amount of energy gained or lost by an electron when it moves through a potential difference of one volt

FORMULAE

eV = half m (v)(v)
E   = (h)(f)
hf   = E2 -E1
E   = m(c)(c)

CATHODE RAYS

Streams of high speed electrons moving from the cathode are called CATHODE RAYS

THERMIONIC EMISSION

THERMIONIC EMISSION is the giving off of electrons from the surface of a hot metal.
