Question
Chapter 19, Problem 31E
Interpretation Introduction
Interpretation: Date of detonation of first atomic bomb is given. Percentage of strontium
Concept introduction: A process through which an unstable nuclide loses its energy due to excess of protons or neutrons is known as radioactive decay. Decay constant is the quantity that expresses the rate of decrease of number of atoms of a radioactive element per second. Half-life of radioactive sample is defined as the time required for the number of nuclides to reach half of the original value.
To determine: Percentage of strontium

5. Draw molecular orbital diagrams for superoxide (O2¯), and peroxide (O2²-). A good starting
point would be MO diagram for O2 given in your textbook. Then: a) calculate bond orders in
superoxide and in peroxide; indicate which species would have a stronger oxygen-oxygen bond;
b) indicate which species would be a radical.
