After stirring salt in a container of water, the salt will dissolve. When adding more salt, eventually the salt will not dissolve. Which of the following refers to a substance that can no longer dissolve in a liquid? * A. boiling point
B. melting point
C. saturation point
D. all of these

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.
