Class notes

Atomic number and mass

When we write an element's symbol we often include two numbers. These are written to the right of the symbol. The atomic mass ( its always bigger). The other number is the atomic number. Here is an example Carbon has an atomic mass of 12 and its atomic number is 6.
Atomic mass = the atomic number (this is the number of protons) + the number of neutrons.
Atomic number = the number of protons.
the number of protons = the number of electrons.


REview of Solid Liquid Gases

yr 8 SLG photo.JPG
Solid Liquids and gases. As you increase the energy of a solid it melts to become a liquid. Even more energy will boil it to become a gas. The transformation names are also shown



The arrangement of electrons around the nucleus is unique to each element when in its natural state. The diagram below shows the pattern. In this example there are 2 electrons in the innermost oribital (there can only be a maximum of 2 in this orbit and it must be filled before the next orbit can be populated.
in this example there are 5 electrons in the outer orbit. This orbit will have a maximum of 8 electrons.
so for nitrogen that has an atomic number of 7 and an atomic mass of 14 it will have 7 electrons that have a negative charge orbiting the nucleus that will have 7 protons that have a positive charge. These charges are equal therefore thet balance out.

using the rules above we can calculate the number of protons. We always assume electrons weigh zero as they are extremely tiny about one billionth the mass of a proton. So the atomic mass is the combined mass of protons and neutrons. So if we know the atomic mass is14 and the atomic number ( ie proton number) is 7 then the number of neutrons must be 14-7=7 neutrons. Go below to review the first twenty elements .
yr 8 Nitrogen structure photo.JPG
Atomic mass = number of protons + number of neutrons






Looking for Similarities Prac
Grouping Elements

Conclusion
Metals are all those elements that can conduct electricity, bend and are shiny. Non metals are dull , brittle and can not conduct electricity. Metaloids have some properties of metals eg shiny and conduct electricity. But they also have non metal properties like being dull or brittle.


Ques 7 Two suitable groups for our elements would be metals (Zn, Sn, Cu) and metalloids (C, Si)
S is a non metal

Ques 8 The element that does not seems it could be in ether group is S

Conclusion
All metals can conduct electricity and are shiny when cut and can be bent.
Carbon in the form of graphite conducts electricity BUT carbon in the form of diamonds or coal does not. (this is because of the way the carbon atoms bond with each other in each of theses forms. Carbon in graphite makes layers )

HMWK: - learn the symbols and name of the elements in our table.

Complete the ques 1- 7 p 245.

The periodic table

This is a useful tool because it tells you
  1. the atomic mass
  2. the atomic number
  3. and the position of the element in the table tells you how the electrons are arranged and orbit around the nucleus.
