24 and 25 are true.
23. The statement "Beta particles are the same as helium nuclei" is false. Beta particles are high-energy electrons or positrons that are emitted during certain types of radioactive decay. On the other hand, helium nuclei consist of two protons and two neutrons, also known as alpha particles.
To understand this, you can study the different types of radioactive decay. Beta decay involves the conversion of a neutron or a proton in the nucleus, resulting in the emission of a beta particle (an electron or a positron). Helium nuclei, or alpha particles, are emitted during alpha decay, which involves the release of two protons and two neutrons from the nucleus.
24. The statement "Gamma rays and visible light are two types of electromagnetic radiation" is false. Gamma rays and visible light are both forms of electromagnetic radiation, but they differ in terms of their energy and wavelength.
To understand this, you can explore the electromagnetic spectrum, which encompasses a range of electromagnetic radiation. Gamma rays have the highest energy and are associated with high-frequency electromagnetic waves, while visible light falls into a specific range of lower-energy wavelengths that our eyes can detect.
25. The statement "Transmutation is the change in a nucleus due to the change in the number of protons" is false. Transmutation refers to the conversion of one element into another by changing the number of protons and/or neutrons in the nucleus.
To understand this, you can learn about nuclear reactions and how they can lead to transmutation. For example, in an alpha decay, the parent nucleus loses two protons and two neutrons (an alpha particle), resulting in the formation of a daughter nucleus with a different atomic number.
26. The statement "In a nuclear equation, only nuclei are represented" is true. In a nuclear equation, you typically represent the reactant and product nuclei, along with any particles or radiation emitted during the reaction.
To understand this, you can study how to write nuclear equations. For example, in a typical alpha decay reaction, the reactant nucleus is represented on the left side of the equation, an alpha particle is shown as a helium nucleus on the right side, and the resulting daughter nucleus is also shown.
28. The statement "Any radioactive isotope can fission" is false. Fission refers specifically to the process of a heavy nucleus splitting into two or more smaller nuclei, accompanied by the release of a large amount of energy. Not all radioactive isotopes are capable of undergoing fission.
To understand this, you can explore the concept of nuclear fission and the specific conditions required for it to occur. Fission primarily occurs in certain heavy isotopes, such as uranium-235 or plutonium-239, when they are bombarded with thermal neutrons.
