The Early Periodic Table C3.1 By the 1860's over 50 elements had been discovered. So scientists attempted to sort the elements into a logical sequence. There were two main scientists that contributed to sorting the elements. These were, ...

Group 7 - Halogens Group 7 elements are known as 'Halogens' Group 7 is made up of fluorine, chlorine, bromine, iodine and astatine All Group 7 elements have 7 electrons in their outer shell so they all react by gaining one electron to f...

Group 1 - Alkali metals Group 1 metals are known as the 'alkali metals'. Group 1 metals include lithium, sodium and potassium. As you go down group 1, the alkali metals become more reactive - the outer electron is more easily lost beca...

About the periodic table notes
GoConqr OriginalUsing the periodic table notes
Start with Elements and isotopes for an introduction to elements and the table’s layout. Its notes on columns provide a useful starting point before you focus on particular groups.
For a closer look at those groups, the listing includes notes on alkali metals and halogens. Transition Metals - The Basics offers another place to focus. If you are revising periodicity, Periodicity: Boiling Points lets you concentrate on one property.
Moving between formats
Read a section of notes, then close it and write down the points you remember. Reopen the note to check what you missed. You can repeat this with another group or property, depending on what you are studying.
When you want to test your recall, switch to a quiz on the unit page. A mind map may be useful when you want to see connections between topics. Pick a note and start with a section that matches your revision.
Frequently asked questions
Which note is a good place to start?
Elements and isotopes is a useful starting point if you want to review elements and the layout of the periodic table. From there, you can move to notes on a particular group, such as the alkali metals or halogens, or focus on periodicity.
What topics do the notes cover?
The listing includes notes on the early and modern periodic table, elements and isotopes, groups of elements, transition metals and periodicity. There are also notes devoted to particular properties, including boiling points and ionisation energies, so you can choose a narrower topic for revision.
Are the notes free to use?
Yes. Every note listed here is free to open and study without an account. The resources were made by GoConqr users rather than GoConqr. A free account also lets you make your own notes, quizzes, mind maps and flashcards, and save quiz scores.
