What is It
Elements and Compounds are all around us. Elements are made up of atom
or atoms of the same kind. They are the simplest type of matter and cannot be broken
down into components. Each element is made entirely from one type of atom. Each
element is unique, and no two elements have the same set of properties. Some are in
the same state, but they have different properties. Some elements are metals like
iron, gold, and silver. Others are nonmetals like Nitrogen, Oxygen and Hydrogen
There are elements that are non-metalloids like Boron, Silicon and Germanium
Compounds are combination of two or more elements like water which is a
combination of Hydrogen and Oxygen; salt which is made up of sodium and chlorine;
and rusts formed when an iron reacts with oxygen. Compounds can be broken down
into its components through a chemical process and formed when two elements are
combined. It has unique properties that are different from the properties of the
elements that make them up.
