This is a presentation that I had made on RUTHERFORD’S MODEL OF AN ATOM. Hope people find it useful...

1. RUTHERFORD’S MODEL
OF AN ATOM

2. INTRODUTION
When we picture a diagram of an atom,
most of us think of a small circle with rings
around it going in several different
directions. This is the Rutherford model of
the atom. Though it is no longer the most
accurate representation of an atom, at the
time Rutherford's model was revolutionary.

3. ABOUT THE MODEL AND RUTHERFORD
• In many ways, the Rutherford model of the atom is the classic
model of the atom, even though it's no longer considered an
accurate representation. Rutherford's model shows that an atom
is mostly empty space, with electrons orbiting a fixed, positively
charged nucleus in set, predictable paths. This model of an atom
was developed by Ernest Rutherford, a New Zealand native
working at the University of Manchester in England in the early
1900s. Rutherford spent most of his academic career researching
aspects of radioactivity and in 1908, won the Nobel Prize for his
discoveries related to radioactivity. It was after this that
Rutherford began developing his model of the atom.

5. DEFINITION
• Rutherford atomic model, description of the structure of
atoms proposed (1911) by the New Zealand-born physicist
Ernest Rutherford. The model described the atom as a
tiny, dense, positively charged core called a nucleus, in
which nearly all the mass is concentrated, around which
the light, negative constituents, called electrons, circulate
at some distance, much like planets revolving around the
Sun. The Rutherford atomic model has been alternatively
called the nuclear atom, or the planetary model of the
atom.
