Concept explainers
Interpretation:
The relationship of isotopes half-lives and stability should be explained.
Concept Introduction:
An element containing isotopes which are emitting radiations are known as radioactive isotopes. This can emit radiation because of instability its nuclei. Isotopes which are having balance numbers of protons and neutrons are stable, but the serious imbalance can lead to nuclear reaction.
Half-life is defined as a time required for decaying one-half part of any sample which is a radioactive material. Some elements are having isotopes that decay and disappear in a day while some can remain radioactive for billions of years.

Generate a molecular orbital diagram but this time using a different approach that draws on your knowledge and ability to put concepts together. First use VSEPR or some other method to make sure you know the ground state structure of the molecule. Next, generate an MO diagram for BH2. Sketch the highest occupied and lowest unoccupied MOs of the BH2 fragment. These are called frontier orbitals. Now use these frontier orbitals as your basis set for producing LGO's for B2H6. Since the BH2 frontier orbitals become the LGOS, you will have to think about what is in the middle of the molecule and treat its basis as well. Do you arrive at the same qualitative MO diagram as is discussed in the book? Sketch the new highest occupied and lowest unoccupied MOs for the molecule (B2H6).arrow_forwardQ8: Propose an efficient synthesis of cyclopentene from cyclopentane.arrow_forward
