Elements And Compounds

ELEMENTS, COMPOUNDS & MIXTURES

MATERIAL CLASSIFICATION

DIFFERENTS OF ELEMENT AND COMPOUND 





Elements can take form of single atom or combination of two or more identificals atom. Compounds is combination of different atom. Elements have same name/symbol and properties with atom. Compound have different properties from its atom/elements composed. Elements can be atom or molecule. Compounds just can be molecule.

DIFFERENTS OF MIXTURE AND COMPOUND 1. Compound is composed of various element with constant ratio and mixture have inconstant ratio of element. 2. Compound have different properties from its composed and mixture have same properties with its composed. 3. Compound more difficult to decomposed in to its part substances.

ELEMENT CLASSIFICATION 

Metallic Elements Examples :Natrium (Na): The most find element at the sea, Lithium (Li) : Usualy find in battery, Calsium (Ca) one of element in skeleton , Magnesium (Mg), Aluminium (Al), Besi (Fe), Tembaga (Cu), Titanium (Ti): The material that more strength from steel but more light, Seng (Zn), Emas (Au)



Metalloid Elements : Examples, Boron (B), Silicon (Si)



Non Metallic Elements Examples : Oksigen (O) : The most find element in the world, Nitrogen (N), Hidrogen (H), Carbon (C), Fosfor (P), Belerang (S), Clor (Cl), Brom (Br), Iod (I)

( the differents of mettalic and non metallic elements can you find in your LKS KIMIA at page 17 )

How to write and give manes of compound 1. If compound is composed from 1 metallic and non metallic : The first name came from metallic and second name from non metallic with added by “ -ida”, examples : Na + Cl = NaCl = Natrium Clorida

2. If compounds is composed from 2 or more element from non metallic : The first name every element added with sum of atom in yunani and the end element added with “ –ida”
