If you mean oxygen: like most elements, it has both stable isotopes, and unstable (i.e., radioactive) isotopes. 16O, 17O and 18O are stable; the unstable (radioactive) isotopes include 15O and 14O.
No, the size of a radioactive sample does not affect its half-life. The half-life is a characteristic property of a radioactive isotope, defined as the time it takes for half of the radioactive atoms in a sample to decay. This property is intrinsic to the isotope itself and remains constant regardless of the amount of material present. Thus, whether you have a small or large sample, the half-life will remain the same.

In photosynthesis, water (H₂O) is split during the light-dependent reactions, releasing oxygen and producing energy-rich compounds. If a photosynthesizing plant is exposed to water containing radioactive hydrogen (H) and radioactive oxygen (O), the radioactive hydrogen will be incorporated into glucose and other organic molecules, while the radioactive oxygen will be released as a byproduct during the formation of molecular oxygen (O₂). Thus, radioactive H will appear in the glucose, and radioactive O will be found in the released O₂.

Yes, Ac (Actinium) and Ra (Radium) are radioactive elements, while Si (Silicon) is not inherently radioactive.
They are all words that have all of the vowels (A, E, I, O, U) in alphabetical order.
N O R M stands for Naturally Occurring Radioactive Material. It refers to materials that contain radioactive elements found in the Earth's crust and can be present in pipeline operations, posing potential safety and health risks if not managed properly.

O-15 is the nuclear symbol for oxygen-15, which has 8 protons and 7 neutrons. It is a radioactive isotope of oxygen often used in medical imaging studies.
