Its mineral composition.
The most useful physical property for identifying galena would be its metallic luster and its high density. Galena has a metallic luster and is one of the densest minerals, so these characteristics can be helpful in distinguishing it from other minerals.
The property most useful for the identification of sulfur is its characteristic smell, often described as similar to that of rotten eggs.
Luster is typically considered the least useful mineral property, as it does not provide much information about the mineral's identity or composition. Luster simply describes how light is reflected off the surface of a mineral, such as metallic, glassy, or dull, and can vary even within the same mineral species.
The most useful physical properties for identifying minerals are color, luster, hardness, cleavage, fracture, streak, and specific gravity. These properties help geologists distinguish between different minerals based on their unique characteristics.
Some of the most useful physical properties of minerals include hardness (measured on the Mohs scale), cleavage and fracture (how a mineral breaks), color, streak (color of mineral powder), luster (appearance of a mineral's surface), and crystal habit (the shape in which a mineral naturally occurs). These properties help identify and classify minerals.
In classifying rocks, there are many properties that can be useful. In my opinion, either color or texture is most useful in classifying a rock or mineral.
The most useful physical property for identifying galena would be its metallic luster and its high density. Galena has a metallic luster and is one of the densest minerals, so these characteristics can be helpful in distinguishing it from other minerals.
I consider that this information is the electronegativity.
The property most useful for the identification of sulfur is its characteristic smell, often described as similar to that of rotten eggs.
Magnetism would be the most useful physical property for separating fine saw dust and salt. However, since neither is magnetic, a process of dissolving the salt in water, filtering out the saw dust, and boiling away the water is necessary.
Density is the least useful property for identification because different specimens of the same type of mineral can vary in size. -Color is the least useful property for identification because it is the most obvious property.

The property that would be most useful in telling hematite and magnetite apart is magnetism. Magnetite is strongly magnetic, whereas hematite is not magnetic. This distinction can help differentiate between the two minerals.
I think to structure, hardness and color.
Hydrogen is a chemical property because it is a pure substance and it cannot be broken down into simpler substances by physical means. It is the simplest and most abundant chemical element in the universe.
The most useful property of semimetals is their intermediate electrical conductivity, which allows for applications in electronics and semiconductors. Semimetals also exhibit interesting properties such as Dirac cones and topological insulating behavior, making them valuable for research in quantum materials and physics.
