Isotopes

Which of the following are the characteristics of isotopes of an element? (i) Isotopes of an element have same atomic masses. (ii) Isotopes of an element have same atomic number (iii) Isotopes of an element show same physical properties. (iv) Isotopes of an element show same chemical properties.

Which of the following are the characteristics of isotopes of an element? (i) Isotopes of an element have same atomic masses. (ii) Isotopes of an element have same atomic number. (iii) Isotopes of an element show same physical properties. (iv) Isotopes of an element show same chemical properties.

Assertion : Isotope is possible because of the using a mass spectrometer. Reason : Separation of isotope is possible because of the difference in electron number of isotope.

We all know that a large number of elements exist as isotopes. The isotopes of an element have same atomic number but different mass numbers. The isotopes. With higher mass number are mostly radioactive in nature. These are called radioisotopes. These isotopes have a wide range of applications. (i) Which isotope is used to study the kinetics of photosynthesis ? (ii) Name the isotope which can detect a blood clot. (iii) Which isotope is used to detect the deformity in bones, if any ?

The half life of a radio isotope is 3h. The mass of the isotope at time t=0 is 160 gm. What is the mass of the isotope left after 15 h ?
