Q: What has atoms with unstable nuclei? Read this paragraph and choose the correct option from the provided answers: A radioisotope has atoms with unstable nuclei. Unstable nuclei naturally decay, or break down. They lose energy and particles and become more stable. As nuclei decay, they gain or lose protons, so the atoms become different elements. This is illustrated in the Figure below . The original, unstable nucleus is called the parent nucleus. After it loses a particle (in this case a type of particle called an alpha particle), it forms a daughter nucleus, with a different number of protons. Choices: - hydrocarbon - microwaves - radionuclide - radioisotope A:
radioisotope

Q: Are zeroes that show only where the decimal point fall significant or not significant? Read this paragraph and choose the correct option from the provided answers: Zeros that show only where the decimal point falls are not significant. For example, the number 470,000 has just two significant figures (4 and 7). The zeros just show that the 4 represents hundreds of thousands and the 7 represents tens of thousands. Therefore, these zeros are not significant. Choices: - neither - sometimes significant - significant - not significant A:
not significant
