isotone means same element having no of protons different from no of nutron

Answer 2

Answer:

• The methyl group (CH3 ) is formed from methane, CH4. The ethyl group , C2H5 , is formed from ethane, C2H6. Two different alkyl groups can be formed from propane, CH3CH2CH3. Removal of a hydrogen atom from one of the carbon atoms at the end of the chain forms C3H7 .

• Isotones are atomic species that share the same number of neutrons, and differ in the number of protons.

• Examples of isotones include carbon-12, nitrogen-13 and oxygen-14. These atoms all have six neutrons and six, seven and eight protons respectively.
