Number One

Physics is about examining forces, energy and motion between objects. It attempts to examine how things interact from a mathematical point of view. It explores the diversity of energy in motion (kinetic) and stored (potential).

Chemistry is about exploring how individual atoms have their own unique properties and how these properties help to explain how groups of may behave.

An atom is a self contained moving object with a center, called the nucleus and a cloud of electrons that surround that nucleus.

Each atom can provide and or store energy.

The structure of an atom influences how it interacts with other atoms.

Many models of the atom are misleading. Lets explore why..

(see list below)

·      Family verses period

·      Proton verses neutron and electron

·      Nucleus and orbital

Combining Atomic theory with how atoms bond

The idea of “electron glue”

When atoms combine, electrons are moving.

Concept to compare

·      ionic verses covalent bond

4.1

All work up to and including bohr model

·      Only one model of the atom is correct.

·  The electrons in an atom orbit its nucleus like planets in our solar system orbit the sun

·  Electron clouds are pictures of electrons in their orbits.

·  The electron cloud is like a rain cloud, with electrons inside of it like drops of water.

·  An electron cloud has electrons in it, but the cloud itself is made of some other material.

·  Hydrogen is a typical atom.

·  Electrons are larger than protons.

·  Electrons and protons are the only fundamental particles.

·  The current model of the atom is the right model.

·  Atoms can disappear after time.

·  Atoms are microscopic versions of elements—hard or soft, liquid or gas, and so forth.

·  Atoms can be seen with a microscope.

·  Atoms move, so they are alive.

·  An electron shell is hard, like an eggshell.

·  Atoms “own” the electrons in their orbits.

Exam for Physics..Monday 23rd

A neutron walks into a restaurant and orders a couple of cokes. As she is about to leave, she asks the waiter how much she owes.  The waiter replies, “For you, No Charge!!!”
