PLC Convention 2018

A very meaningful experienced at PLC BMKPM Convention 2018 at The Jerai Hotel, Alor Setar Kedah on 5-7 Oktober 2018. Presenting a PLC paper about Jotter Book's Rubrics.

Differences of Atoms, Molecules, Elements, Compound and Mixture

The terms above are the most confusing terms for students 💫. Many students ask me what the differences between them?. or some of the terms refers to the same meaning? so, lets check it outt....😉

Atoms 
Atoms is the smallest particle of an element that retains the chemical properties of element. The atoms of many elements are bonded together in groups to form particles called molecules. Atoms consist of three main types of smaller particles such as protons, neutron and electrons

Molecules 
Molecules is the smallest particles of an element or compound that normally exist on its own and still retains its properties

Elements
A substance which cannot be split into a simpler substance by chemical reaction. There are just over 100 known elements classified in the periodic table

Compound
A combination of two or more elements bonded together in some way. It has different  physical and chemical properties from the elements it is made of. Compound are often difficult to split into their elements. The proportion of each element in a compound is constant example water (H2O) is always formed from two parts of Hydrogen and one part oxygen

Mixture
A blend of two or more elements and/or compound which are not chemically combined. The proportion of each elements or compound are not fixed and each keep its own properties. A mixture can usually be separated into its elements or compounds fairly easily by physical means

Hope thats help!
