To address this question, let's first understand what an alpha particle is.
An alpha particle is basically a helium nucleus. It consists of two protons and two neutrons. This configuration can be denoted using nuclear notation as [tex]\( ^4_2 \text{He} \)[/tex], where the superscript 4 represents the mass number (total number of protons and neutrons), and the subscript 2 represents the atomic number (number of protons).
The notation given in the problem is [tex]\( \frac{4}{3} \text{He} \)[/tex]. However, this notation is incorrect because it implies that the helium nucleus consists of 4 nucleons (protons and neutrons) but only 3 protons, which is not possible for a helium atom. Each helium nucleus must have exactly two protons.
Since the given notation [tex]\( \frac{4}{3} \text{He} \)[/tex] is not a correct representation of an alpha particle, the correct answer to the question "The alpha particle (a) is: [tex]\( \frac{4}{3} \text{He} \)[/tex]" is:
False
