Relation between average life time `(tau)` and half-life `(T_(1/2))` is

The time of decay for the nuclear reaction is given by t = 5 t_(1//2) . The relation between average life tau and time of decay (t) is given by a. 3 tau "In" 2 b. 4 tau "In" 2 c. 5 tau "In" 2 d. 6 tau "In" 2

The correct relation between t_(av) =average life and t_(1//2)= half life for a radioactive nuclei.

The relationship between distintegration constant (lambda) and half-life (T) will be

The activity of a nucleus is inversely proportional to its half of average life. Thus, shorter the half life of an element, greater is its radioactivity, i.e., greater the number of atomsd disintegrating per second. The relation between half life and average life is t_(1//2) = (0.693)/(lambda) = tau xx 0.693 or tau = 1.44 t_(1//2) The half life of a radioactive element is 10 years. What percentage of it will decay in 100 years?

The activity of a nucleus is inversely proportional to its half of average life. Thus, shorter the half life of an element, greater is its radioactivity, i.e., greater the number of atomsd disintegrating per second. The relation between half life and average life is t_(1//2) = (0.693)/(lambda) = tau xx 0.693 or tau = 1.44 t_(1//2) Mark the incorrect relation.

The relation between half life and average life is t_(1//2) = (0.693)/(lambda) = tau xx 0.693 or tau = 1.44 t_(1//2) The half-life periods of four isotopes are given 1 = 6.7 years, II = 8000 years, III = 5760 years, IV = 2.35 xx 10^(5) years. Which of these is most stable?

For the first-order reaction T_(av) (average life), T_(50) (half-life) and T_(75) (time 75% reaction) are in the ratio of
