__ Atomic structure __
 * Lesson section 1c atomic structure **
 * [|www.echalk.co.uk] **
 * echalk2@dulwich-shanghai.cn **
 * echalk **
 * “Building your own atom”. **

Use the above animation on echalk to help you to learn the learning objectives below (M11). Only when you feel you have mastered a learning objective can you move on to the next. In the animation:
 * 1) Read the instructions.
 * 2) Using some of the learning objectives below to attempt to build a number of atoms with __all__ 3 types of subatomic particles in the correct place in the atom.
 * 3) You should also work out what information the mass number and atomic number give you about the structure of an atom.
 * 4) Once you have completed an atom, click on the "choose an element" tab, find your element that you have made the atom of and find a link between the atom and the information about the element in the periodic table.
 * Learning objectives (M19) ||
 * know the structure of an atom in terms of the positions, relative masses and relative charges of sub-atomic particles. ||
 * know what is meant by the terms atomic number, mass number, isotopes and relative atomic mass (Ar) ||


 * Learning objective (M11) ||  ||
 * * Know the structure ||  ||
 * * Recall that electrons move around or orbit around it in shells or energy levels ||  ||
 * * Know the relative charge and relative mass of a proton, electron and neutron ||  ||
 * * Know what the atomic number is and what information it gives ||  ||
 * * Know what the mass number is and what information it gives ||  ||
 * * Know how to calculate the number of protons, neutrons and electrons in an atom when the atomic number and mass number are given ||  ||
 * * Recall the number of electrons that can orbit in each energy level ||  ||
 * * Be able to draw an atom of the first 20 elements in the periodic table showing __all__ the electrons. ||  ||

Once you feel you have mastered __all__ of them, go onto handout 1c and work through page 1 and the top of page 2.

__ Isotopes __

When you get to isotopes on page 2 of the handout, go to http://www.brainpop.co.uk/science/materials/isotopes/ and log in dulwichcollegeshanghai1/shanghai

Now complete the table on page 2.

__ Relative atomic mass __

Look at the sample calculation at the top of page 3 and complete the table below it.

__ Electron arrangement and the periodic table __

Read this section on pages 3 and 4 in the handout and complete the task on page 4 (the table). Once you have completed the table answer the following questions - you can also use echalk: "electronic structure:visual database" Do worksheet " Electron arrangement".
 * What information does the group number give about the atoms in that group?
 * What information does the period number give about the atoms in that group?

__ Test yourself __

On echalk, play the “atomic structure bounce quiz” and “electron configuration pairs”. Do the questions on page 12 in your textbook.
