ISOTOPES

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.

What is Isotope?

Define Isotope

The isotope of ""_(92)U^(238) decays by alpha -emission to an isotope of thorium (Th). The thorium isotope decays by beta -emission to an isotope of protactinium (Pa). Write down the equation to represents these two nuclear charges.

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 ?

Define isotopic number. Calculate the isotopic numbers of hydrogen-3 and chlorine-37
