Classify the elements based on atomicity with examples. |
|
Answer» Solution :The number of atoms that constitute a MOLECULE of an element is CALLED atomicity of that element. A molecule of HYDROGEN is MADE up of two atoms and hence its stomicity is two. BASED on the atomicity, elements can be classified as follows: (i) Monoatomic elements : The elements in which each molecule contains only one atom. Example : `Cu,Ag,He` etc (ii) Diatomic elements : The elements in which each molecule contains two atoms. Example : `H_(2),O_(2)N_(2)` etc (iii) Polyatomic elements : The elements in which each molecule contains more than two atoms. Example : `O_(3),P_(4),S_(8)` etc |
