CONCEPT MAP

ELEMENTS

The properties of an element:

    An element is a pure substance (single matter) CAN’T BE broken down into simpler substances by chemical reaction.  

     An element consists of only one kind of atom.

An element is made of tiny particles called atoms. 

Atom is the smallest part of an element.

For examples,

JUST INFORMATION ABOUT ATOM:

The parts of the atom, you can look at the picture below:

The difference lies in the number of protons or electrons contained in the atom.

For example, you can see it on the periodic table:
