Question

The decay constant for the element x is 6.931 yr⁻¹. what is the half-life?

Answer 1

0.1 years

Step-by-step explanation:

if the decay constant is represented by x, the half life of an element can be determined by the formula: t(1/2)=ln(2)/x. so fill in the given decay constant and solve the formula; the answer is 0.1 years
