Answer 2

elements

• A substance containing atoms of the same type

• It has only one type of atom, with each atom having its own atomic number

• The representation of an element takes place by using a symbol  

• Breaking down of elements into more simple substances by using chemical reactions is not possible

• Oxygen(O), Hydrogen(H), Chlorine(Cl), Sodium(Na) etc

compounds.​

• A substance having atoms belonging to a combination of  different elements

• They have different elements whose arrangement is in a definite ratio through chemical bonds

• The representation of a compound is by using a chemical formula

• Breaking down or separation of compounds into more simple substances by using chemical reactions is certainly possible

• Sodium chloride(NaCl), Water(H2O) etc
