ability to rust
Answers
Final answer:
The ability to rust is not a physical property of matter, but a chemical one, reflecting a substance's capacity to react with oxygen to form a new substance.
Explanation:
In the list provided, the ability to rust is NOT a physical property of matter. Physical properties include traits that can be observed or measured without changing the composition of the material. Examples include melting point, boiling point, odor, and density. The ability to rust, however, is a chemical property as it indicates a substance's ability to react with oxygen to form a new substance, which involves a change in composition.

What is stained glass?
Stained glass is defined as a glass material which is made colored by means of adding metallic salts during the manufacturing process which imparts color to the glass.
These are used in many decorative purposes like decorating windows . The colors are imparted to the glass by mixing metal oxides into the colorless glass in its melted state.Sometimes fusion of a colored glass with a plain glass to make a stained glass is also used.
Stained glass is also prepared by glass paint where in streaks are introduced in glass by means of light firing in a furnace or a kiln.Silver stain is a range of compounds where in silver compound are mixed with binding substances and then applied to surface of glass,which are then fired in a furnace or in a kiln.

Neutron capture reactions.
Explanation
Isotopes of the same element have the same number of protons in each nucleus. However, their nucleus differ in the number of neutrons. Adding one or more neutrons to a nucleus will converts it to a different isotope of the same element.
Neutrons can be produced with a particle accelerator. The researcher might aim fast moving alpha particles from the accelerator at a beryllium Be target.
Doing so will convert beryllium-9 to carbon-12 and release one neutron.
The neutron produced in this process moves very fast ("fast neutrons"). It might knock protons or alpha particles off the target nucleus. This is undesirable since the nucleus will have a change in its proton number. It will end up belonging to a different element.
The researcher should reduce the speed of those neutrons. Passing neutrons through moderators greatly reduces their speed. Moderators are materials that are rich in light nuclei. They remove the energy of neutrons as the two collide. Examples of moderators are heavy water (D₂O) and graphite (carbon). Slow neutrons are easier to capture than fast-moving ones. Combining those slow-moving neutrons to the source isotope will likely produce a different isotope of the same element.

Sodium has 11 electrons, and in its ground state, 8 of these electrons are located in the second principal energy level.
The total number of electrons in the second principal energy level of a sodium atom in the ground state can be determined by understanding the electron configuration of sodium.
Sodium (Na) has an atomic number of 11, which means it has 11 electrons. In the ground state, these electrons are distributed in various energy levels. The second principal energy level, often denoted as n=2, can hold a maximum of 8 electrons. The first energy level, n=1, can hold a maximum of 2 electrons.
To find the number of electrons in the second energy level, we first fill the first energy level with 2 electrons and then place the remaining 9 electrons in the second energy level. However, since the second energy level can only hold 8 electrons, sodium's electron configuration in the ground state is 2-8-1, where 2 electrons are in the first energy level, 8 electrons are in the second energy level, and 1 electron is in the third energy level.
So, there are 8 electrons in the second principal energy level of a sodium atom in the ground state.
