Explanation

• Isotopes are atoms of the same element.
• They have the same number of protons but different neutrons.
• Due to different neutrons, their mass numbers differ.
• Example: Carbon-12, Carbon-13, Carbon-14.
• They show same chemical properties but different physical properties.

Explanation

• Gamma rays have the highest penetrating power among these particles.
• Due to their lack of mass and charge.
• It allowing them to pass through most materials.

Additional information:

• Alpha radiation has the lowest penetrating power.

Explanation

• Isobars are atoms of different elements with the same mass number.
• They have different atomic numbers (protons).
• They represent different chemical elements but equal total nucleons.
• The concept of isobars was introduced in nuclear chemistry.
• It studies by Alfred Walter Stewart.
• Also later refined by Frederick Soddy.
