Broxi bear reduces permanganate ions one electron at a time

Demonstrate understanding of thermochemical principles and the properties of particles and substances

 

 

                   

Lewis structures also known as Lewis diagrams are diagrams that show the bonding between atoms of a molecule and lone pairs or non bonding electrons. Using these structures it is possible to predict the shapes of covalent molecules.

Working out Lewis structures involves the use of an arcane set of rules the only justification for which is that they appear in chemistry text books and examinations.

There is an app for this. Learn how to construct the diagrams but use the app to check answers. It works by plugging the formula. You don”t need  to use subscripts.

For example

methane CH4

sulphuric acid H2SO4

You can also type in the name methane.

Introduction to the periodic table, home learning.

Introduction to the periodic table and quiz

Elements sit on the periodic table so that atoms with similar properties lie in the same column

Work through The Introduction to the Periodic Table Prezi then do the quiz to check your understanding.

By the end of this unit you should know:

 

  • what the atomic number and mass number of an element is.

  • how elements are arranged on the periodic table.

  • what Periods and Groups are.

  • the physical and chemical properties of the group 1 metals.

  • the physical properties of group 17 elements.

  • the physical properties of group 18 elements

  • that sodium and chlorine react violently together.

  • that elements in the same group have similar properties. WHY!
