Answer 1

Answer:

Isotopes

Isotopes are the atoms of same element having same atomic no. but different mass no.

• Isotopes of hydrogen
• Isotopes of carbon
• Isotopes of oxygen

Radioactive isotopes

The isotopes which are unstable due to presence of extra nucleus in which their nuclei and emit various types of radiations are called radioactive isotopes.

Examples-

• Uranium 235
• Uranium 235Carbon 14
• Uranium 235Carbon 14Sodium 24

Applications of radioactive isotopes

• Radioactive isotopes are used in the treatment of cancer.
• Radioactive isotopes are used in the treatment of disease like goitre.
• Radioactive isotopes are used as a fuel in nuclear plant for generating electricity.

Hope it helps...

Answer 2

Answer:

Radioactive isotopes are effective tracers because their radioactivity is easy to detect. ... Tracers can also be used to follow the steps of a complex chemical reaction. After incorporating radioactive atoms into reactant molecules, scientists can track where the atoms go by following their radioactivity.
