Answer :
Final answer:
Tungsten-186 decays into Rhenium-186 through a process known as beta minus decay. This is where a neutron transforms into a proton, leading to an increase in the atomic number by one. Hence, the statement is true.
Explanation:
The question states that rhenium-186 is produced from the beta decay of tungsten-186. During beta decay, a neutron in the nucleus of the atom converts into a proton thereby emitting a beta particle, that is, an electron or positron. In this process, the atomic number of the original element increases by one, while the mass number remains unchanged. Actually, tungsten-186 will decay into rhenium-186 only during beta minus decay.
For example, for iodine-131 (referenced above), when it undergoes beta decay, it becomes Xenon-131 as the atomic number increases by one unit (from 53 to 54). Similarly, tungsten-186 (atomic number 74) would turn into rhenium-186 (atomic number 75) via beta decay. Despite that, its mass number stays the same - 186. Hence, the statement is true if it was indeed referring to beta minus decay process.

Final answer:
The statement about the production of rhenium-186 from the beta decay of tungsten-186 is false. Beta decay involves the emission of an electron from a nucleus, which isn't how rhenium-186 is typically produced. Radioactive decays like beta decay are significant in radiation therapy for cancer treatment.
Explanation:
The production of rhenium-186 from the beta decay of tungsten-186 is inaccurate. Beta decay typically involves the emission of an electron from a nucleus, enabling a neutron to convert into a proton. An example of a nuclide that undergoes beta decay is Iodine-131. However, in the case of tungsten-186, beta decay would most likely result in the production of another element such as osmium or hafnium, not rhenium. Therefore, the statement is false.
