This term, I have learnt 2 main topics.
Firstly, I learnt about the periodic table of elements. The periodic table of elements consists of all the different kinds of elements that has been discovered. An element is a pure chemical substance consisting of one type of atom, which is distinguished by its atomic number. This number can be found below the letter of an element in a periodic table. Every element has its own letter to symbolise it. For example, the letter 'H' represents hydrogen. When two or more elements are chemically combined, they become a compound. Similarly, a compound can be separated using separation techniques such as heating the compound, or using electrolysis. However, two elements can be mixed and not combined chemically. This results in a mixture.
Secondly, I learnt about solutions and suspensions. A solution is a mixture of 2 a solute and a solvent. The solute dissolves in the solution to form a solution. Solutions are always clear, although they might have different colours. Suspensions, on the other hand, is never clear. They always have precipitate in them. This is because the substances are not immiscible in each other.
I feel that I have grasped the basics of chemistry and am ready to proceed to the next level
