the Periodic Table

to print out a good one http://elements.wlonk.com/Elements_Pics_11x8.5.pdf

classification of elements into metals and non-metals

examples of metallic elements and their symbols: copper, zinc, aluminium, iron, silver and gold

OC3 understand what an element is and recall that all known elements are listed in the Periodic Table;

An Element is a pure material made from only 1 type of atom.

94 of the elements are found in nature. A further 23 have been artificially created in laboratories, giving a total of 117.

Elements.

An each particle in an element, is the same type of atom. They can be idenitified as being the same type of atom because they each have the same number of protons, neutrons and electrons (usually)

OC8 & OC9

recall the symbols of the elements

Cu, Zn, Al, Fe, Ag, Au, C, O, S, H and N

Following a link we can see a periodic table with the Standard Temperature and Pressure division line between Metals and Non-Metals

http://commons.wikimedia.org/wiki/File:Periodic_table-metals.svg

The staircase line dividing the 2 sections is well quoted, however this is not a steadfast rule though, at high enough pressures Non-Metals show the properties of Metals.

Many of the metals in the world were found in ancient times, and so we use their latin names where they exist for many of the metals.

Cu = cuprum = Copper

Ag = Argentum = Silver

(think what is money in the

Irish or French languages)

Au = aurum, "shining dawn" = Gold

Fe = ferrum = Iron

Hg = hydrargyrum = Mercury

Some metals were not identified when Latin was the most important language, Zinc (Zn) was only found in a very pure form in 1746,

Aluminium (Al) is the most abundant metal in the earth's surface.

The Periodic table is organised because of the way the atoms organise themselves

New Element 112

Prepared to be bored

Group 1: The Alkali Metals

These are the elements in the 1st column on the Periodic Table

Examples are …………………………………………………………………

Draw a Bohr diagram of Lithium, Sodium and Potassium.

• They are all metals

• Have __ electron in their outer shell.

• All want to lose __ electron in order to have a full outer shell.

• Become _____ reactive as you go down the group.

OC49 describe the reactions of the alkali metals with air and water (word equations for reaction with water)

Physical Properties Chemical Properties

1. React with water to form a base (alkali)

Sodium + water → sodium hydroxide + hydrogen gas

• React with oxygen to for alkaline oxides.

Sodium + oxygen → sodium oxide

Group 2: The Alkaline Earth Metals

• Examples are …………………………………………………………….

• Each element has __ electrons in its outer shell.

• _____ reactive than the alkali metals (group 1).

To examine the properties of Alkaline Earth metals

Group 7: The Halogens

• Examples are ……………………………………………………………

• Have __ electrons in their outer shell.

• They all want to _____ __ electron.

• Become ____ reactive as you go down the group.

All elements react in order to obtain a full outer shell.

These elements are said to be 'bonded' to the other element.

There are 2 types of bonding

Ionic & Covalent
