What is the boiling point of a solution prepared by dissolving 194 g of octasulfur (S8, Molar mass = 256.5 g/mol) in 1,249 g of CCIA? Kb = 5.05°C/m, boiling point of pure
CCl4 = 76.7°C)?

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.
