Setler79 [48]

Answer:

An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation or a positively charged ion. The atom gaining one or more electrons becomes an anion which is a negatively charged ion.

Which of the following statements best describes the properties of aluminum-28?
Contact [7]

d. When aluminum-28 undergoes beta decay, silicon-28 is produced.

Explanation:

When the nuclei of aluminium-28 decays, it produces silicon- 28:

    Aluminium    ²⁸₁₃Al

    Silicon 28      ²⁸₁₄Si

    beta particle     ⁰₋₁\beta

       

           ²⁸₁₃Al        →          ²⁸₁₄Si      +        ⁰₋₁\beta

This way, the mass and atomic number are conserved.

Conservation of mass number:

                28 = 28 + 0,  28 = 28

                 13 = 14 -1 ,       13 = 13
