The Fact That Most $\alpha$ Emitters Show a Group of Discrete $\alpha$

question 85

Multiple Choice

The fact that most $\alpha$ emitters show a group of discrete $\alpha$ -particle energies,rather than a single energy,can best be explained by which of the following?

• A)\(\alpha\) particles and \(\beta\) particles are emitted from the same unstable nucleus,and because the \(\beta\) particles exhibit discrete energies,so must the \(\alpha\) particles.
• B)The parent can decay by \(\alpha\) emission to any one of a number of allowed energy states of the daughter.
• C)An \(\alpha\)-emitting parent normally decays to many different daughter elements.
• D)\(\alpha\) emission is accompanied by neutrino emission.
• E)Varying amounts of energy are required to tunnel through the nuclear potential well.

Cyclic Hemiacetals

Compounds formed from the reaction between an aldehyde and an alcohol under acidic conditions, resulting in a ring structure containing both an alcohol and an ether (or alkoxy) group.

Pyranoses

Ring forms of six-membered sugar molecules that result from intramolecular hemiacetal formation, where the oxygen atom is part of the ring.

Furanoses

Ring forms of monosaccharides (sugars) that contain a five-membered ring typically including an oxygen atom.

Glucose

A basic form of sugar that serves as a crucial source of energy for living beings and a fundamental element of numerous carbohydrates.
