11St2 homework task for rates of reaction due Friday 4th October

To support your understanding of the reaction rate topic use this presentation and;

 

add particle diagrams that represent each explanation (you might struggle with catalysts).

 

Then see if you can expand the explanations; put in more detail so that they make more sense.

 Find data or graphs from experiments that support these theories and explain how the evidence supports the theories (PEEL).

Building The Atom Task

 

The atom is made up of two parts,:

  • the positive nucleus in the centre which contains both protons and neutrons

  • Negative electrons that are ‘in orbit’ around the nucleus.

Most of the atom is ‘empty space’.

 

When atoms react chemical bonds are formed between the atoms by the electrons.  These electrons can be lost, gained or shared to form bonds.

 

Making a Model of An Atom

 

 

These are some pictures of atoms.  Try and make a 3D model of an atom that shows the nucleus, protons, neutrons and electrons ‘orbiting’ the nucleus
